going into this video I thought that if we were a more successful and significantly larger outlet then we would probably do things like clickbait titles an example would be our hard drive companies lying to you I think that's what we're talking about today but not quite that extreme because the answer to that is mostly no marketing is always kind of blind but what are you going to do so the question here is from zero on the discord chat for our patreon backers you said what's the difference between a gigabytes and a gig 8 bytes which I think you meant to give a byte and why does Windows represent them incorrectly so we're going to go into that today before we get into that this coverage is brought to you by Thermaltake and their contact silence 12 air cooler it's about a twenty five dollar cooler competes with be hyper 212 but is newer finally and has an for mounting support so get into the content I'm joined by Patrick stone hey who just spent the last bit doing some numbers for this video I like budging numbers yeah it's very fun baby so what I guess the we can do a short answer well let's let but explain the question first sure right so what is what's your interpretation on this question so what I'm hearing is the person wants to know hey I've seen these two different representations of what they believe is a storage measurement what do they mean right so we're going to try to break that down for you guys yeah so in Windows give you an example if you go by a one terabyte hard drive today and you plug it in as many of you know I'm sure it will show up as 931 gigabyte right which where did that number come from not the same yeah so with SSDs if you're not familiar s what these are a bit different than what we're talking today with an SSD you might have over-provisioning a place not to be confused with what we're talking about here right so you buy a 256 gigabyte SSD maybe it shows up as 240 that's generally over-provisioning they tend to be about seven percent not talking about that so then the short answer to this 1 terabyte verse 931 gigabytes it's because of using decimal verses binary unit so yeah for measuring the hard drive capacity different numbering system is to represent the data which is not very consistent oh yeah useful for the user right so do you want to want to dive into a what decimal and binary are in this context yeah absolutely yeah so decimal just means base 10 deci yeah this is usually associated with 10 and so base 10 means you got 10 to whatever power so like 10 to the first power is just going to be you know 10 10 to the 0 power is going to be 1 and tend to the biskits like let's say 10 to the third power is a thousand which they're going to say is a kilo and then binary is a little different their binary means base 2 so you got two to whatever power 2 to the 1 is going to be 2 2 to the 0 is going to be 1 but then if you look at 2 to the 10th power that's 1,024 and here's where the confusion comes in are we talking about 1,024 are always talking about 1,000 right what you need a measurement we deal with and that's where the decimal verses binary confusion comes in so we can figure it out right so drives the hard drives are advertised as using decimal format generally 1 terabyte let's say a decimal format number 500 gigabytes 2 terabytes right there easy to say I like that a windows uses a binary format which do we know explicitly why that is uh no we don't know why when it was actually Microsoft what's going on ah sure there's an actual reason but let's go through some of the two different sort of organizations here si Emily and it's what was the other one yeah so si and then I you see and really that the problem is that there are just so many different standards organizations and each of them decides hey let's do it this way that there is an agreed-upon rule and basically the idea is if it's data measurement we're going to try and use base 2 stuff however the hard drive manufacturers have decided let's not do that and so we're not sure exactly that is if we could get the hold of like Seagate or what's the digital realm I think they can answer that for us right because that would kind of make the world easier and a better place to live in but you know hey solving global crises partying with binary versus decimal how far we have fallen right so difference of hard drive vendors and windows basically is the short answer this yeah we go into a longer answer I think we should probably define more units first you may have seen MIB gid as a unit of measurement yeah not me right please the AI is important here it's not just it's not just like a different spelling of MB or GB yeah exactly so if you're looking at MIB that's maybe bit if you're looking at GID that's Gabi Gabi or Gibby Gibby Gibby there you go yeah pronunciations right but the point is if you have that little the lowercase I in between a capital M and a capital B or a capital G and a capital B that little lowercase I that means you're dealing with the binary system not a decimal system if you have the capital m and the capital B or the capital G and the capital B you might be dealing with binary you might be dealing with decibel depends upon what you're looking at but the thing that you can depend upon is if you feed a little I hit a little I then it's a binary system binary standard numbering right so one give it bite and it's funny as it sounds the real measurement one give a byte is equal to one binary gigabyte yeah that's right yeah okay yeah right and then or I guess 1024 megabytes right there you go binary gigabytes 1024 mega mega bytes excuse me yeah yeah yeah so if you're going to start saying the the AI measurements then you got to stick with the admin right so yeah 1024 gigabytes you guys head yet basically it roughly comes down to one binary gigabyte is equal to 1024 megabytes is equal to roughly ten seventy four megabytes the unit that were generally familiar with that sounds about right that sounds about right Thanks it does the math before we do the video I'll just double check okay so let's let's run through it let's use a 500 gigabyte Drive as an example and just do some calculations here you want to take it away yeah so we'll put some stuff down here on the page for you so that it makes more sense and we'll go from there so it's like this right so let's say you're looking at you go to the store and you buy a 500 gigabyte Drive right so you're looking at 500 gigabytes right and this is what it says on the drive it just says 500 gigabytes so then you're like wait a minute why does my windows show that I have 465 gigabytes all of a sudden and the truth is you need to do some unit conversion like you don't want gigabytes you want to find out what it is and give the bytes so here comes some unit conversion for you guys okay so if I don't want gigabytes I got to figure out how to get rid of gigabytes so I know that one gigabyte is the same thing as one mil 1 billion 1 billion bytes so that's 10 to the 9th okay 10 to the 9th bytes so that looks like this right here okay and what's going to happen is this gigabyte right here that guy is going to cross that with that guy right there so now we got bytes which is that's good which is good that's good nice yeah so now but bytes is not quite what I want I want I want give it legs so now I'm going to say okay well how can I go from bytes to give advice well that's pretty simple I know that 2 to the 30th power and you can look this up on tables like not hard to find 2 to the 30th power bytes is 1 gibibyte GI b so it looks like this right here 2 to the 30th power bytes is 1 gibibyte and look at what happens here now so I got some more unit cancellation I got BAM that guy's gone go away this guy's going go away and now I'm left with only thing over here this guy right here that's beautiful I sort of want baby bytes right there okay so just doing the math here now we're going to do 500 times a billion divided by 2 to the 30th which is a big number so we're going to punch it on the calculator here just got 500 we're going to times that by a billion or 10 to the 9th and then divide that by 2 raised to the 30th power and Steve's doing some Google masses yeah Google's a wonderful thing how my hat yeah I did 4 so we got a funny-looking number right 465 dot and then a big decimal that actually is significant all those points we found out so it's dot six six one two eight seven three zero eight if you care and I'm watching it what is the significance of that number that looks like what we see in window exactly so now you're seeing when windows reports you got four hundred sixty five gigabytes what they actually mean it's four to sixty five gigabytes right and four to six without gigabyte gigabytes is the same thing as a drive manufacturers advertised 500 gigabytes so we're just showing you guys the relationship and even though it appears to be confusing the math does work out you can prove it mathematically and so when you see windows advertise 465 Gibby bites actually windows says four to six out of gigabytes it actually does mean five hundred billion bytes right all right and so we just want you guys to know that if you're paying for five hundred billion bytes you're getting five hundred billion bytes yeah the the bytes are there it doesn't vanish it's not like they're just rounding up they exist true except the how is it calculated what unit are you using to get the number 500 gigabytes versus windows which I think windows rounds down as well yeah we found out well yeah and we were thinking about like what why is it that way and the only thing we got with was okay well if you paid for something like let's say you paid for four hundred sixty six gigabytes but then you only got 460 you'd be kind of upset but if you pay for 465 and then got for sixty five point six be like hey it's got a pre for six yeah so there you go yeah and also also if you if you really like trying to dig down into this stuff if you go into Windows Explorer and you right-click on your drive the one that says 465 gigabytes if you look at the properties to drop you should see five hundred billion bytes available so guys how it works right yeah yeah maybe would you like a little screen cap and you'll see that who knows we'll see yeah yeah and it gets a bit more extreme too of course as you go up in size so one terabyte it looks a lot worse now you're losing about 70 gigabytes and losing of course air quotes there yeah as we've just explained so you know two terabytes looks even worse so so that's why that happens I know it's kind of a basic topic in terms of not something that impacts your daily builds or anything but it's an interesting one and I think this puts some of the numbers behind it but yeah everyone can visualize it better yeah definitely yeah I reckon you know rest assured you're not being cheated everyone should know about you mark yeah mate okay maybe everyone is out to get you we're paid by a big hard drive company one to tell you sit where she'll love the remaining hard drive vendors as they desperately fight off the SSD this is getting very dark thank you for watching as always subscribe for more patreon.com/scishow on helps out directly S at the end of that gamers Nexus and this question came from a discord user we have a discord chat there which you get access to you once you back is on patreon thank you zero for the question we'll see you next time okay hey what do you guys think about the view of like looking at the camera versus just looking at the person
