Yeah, honestly I'm usually so tired of the imperial VS metric debate (I know metric is better and I wish the US used it, it's just a low priority), but drill bit sizes are so stupid.

"Yeah gimme that 15/64ths bit" unhinged behavior.

I like inches, I like the size of 1/8th" it's suitable to my needs. I like the scale on the ruler, my eyes can instantly tell what I'm measuring because each tick is a different length. It works for me, it jives with my tools, I will not buy new rulers.

I would happily throw out all my drill bits and switch to numbered ones or metric, I don't care. Fractions for hole size is dumb. I'll also happily throw out all my imperial sockets and wrenches and switch to one kind of nut. Having two standards of the same tool just sells more socket sets. Which was probably the point.

If only they'd made a metre equal a yard, then everyone would be bilingual and we wouldn't have to fight. You could use the one that was appropriate for the job.

You know if they changed a meter to equal a yard, they would have to change what an amp is. Americans use amps. So it just bites us in the ass anyway.

Edit: I just remembered my definition of amp is out of date. I mean, it might still change, but not as directly as I thought.

Mega is 10^6 , Mebi is 2^20 aka 1024^2 bytes

Edit:

The confusion comes from the fact that Microsoft in Windows calls 1024 bytes a kilobyte, which makes no sense whatsoever, since that word has a meaning and that ain't it.

When MS first launched MS-DOS maybe made sense (maybe), but right now it's only creating confusion. Calling kilobyte a kibibyte is around a 2% error, but with terabyte it's more than 9%, which is a pretty big deal when you buy a 1TB disk and only shows up as 900 and something GB

But it is probably fair to say that MS emboldened storage and networking companies to not change their stance. It doesn't help that it's in their benefit as they're providing actually less product because of the confusion.

I don't agree. It might sometimes be cool, but with a numerical system in base 10, having a unit system in base 12 becomes really hard to manage. Let's take meters:

1m = 10dm = 100cm = 1000mm VS 1m = 12dm = 144cm = 1728mm

How many mm is 15 dm in each system?

To make a base 12 system work, you'd need to change the numerical system also, by adding two new digits, like we do for hexadecimal numbers, so you'd have ...8-9-A-B-10, where A = 10 and B = 11 (in 10 base), so that 1m = 10dm = 100cm but in base 12.

Anyway, good luck trying to pass that, I've seen people who can barely count on their fingers, let alone understand a new base 12 numerical system. And for what?

Because a lot of imperial measurements revolved around being able to be divided by 4, and occasionally 3 at times.

For instance the cooking unit of measurments are in 4's or base 2 in a way (e.g 1 gallon = 4 quarts = 8 pints = 16 cups = 128 ounces)

We still see 4s or 3s irl regardless of measurement system. Doughnuts are often prepared in dozens and virtually never in 10s. Do we walk around claiming why bakers hate 10 step counting?

Time is the example of something designed around 3/4 and didn't change. 60 is divisiable by both 4 (15) and 3 (20) and is not base 10, but people can accept that.

What if you need to represent something between 1/10th and 2/10ths without misrepresenting your precision?

Fractional measurements are way better for indicating precision than decimal. With decimal precision can only be increased or decreased by a power of 10, whereas fractional can be any level of precision - just represent the precision in the denominator.

Any aerospace mechanics have any comments on this matter?

Certified aircraft repairman here: That's not an aviation bolt, so the correct tool to turn it is a pair of vice grips and a hammer.

I'm not an aerospace mechanic, but I do have some insight.

The formula in the image is incorrect. It depicts 7/16" - 10 cents = 10 mm, not plus. Notice that 7/16" indicates the gap in the wrench, and the dime makes that gap smaller.

Now that that is out of the way, it seems that a dime is 1.35 mm (I love that American currency is specified in metric). So, 7/16" - 10 cents = 9.7625 mm. So, pretty damn close to 10 mm.

Wait... 20h old and nobody picked up un the fact that the thing on the picture is actually screw and you'd need a screwdriver for that?
