Cybertruck width ~78" inch / bumper = 72" inch. Got dimensions w/ my measurement tape! 📏 🤣

Scaling a building plan in feet is a real pain, although at that point you should really be blaming the draftsman for not putting enough measurements on the plan. A plan at 1:100 gives you cm for meter, so super easy to do the math.

If you’re drawing old school with a ruler and pencil, the ruler has your conversion right on it. If you’re using CAD, well, you input the original numbers and go from there. Doing math not required.

And if you do this kind of stuff all day long, you have the imperial conversions in memory for the major numbers. For precise things, you know the conversion right off the top of your head. It’s not “hard” vs “easy”.

When I fly into an airport, many of the taxiways are limited to a certain max wingspan. I can tell you my wingspan off the top of my head. And when I fly in Europe, a half second conversion and I can remember what it is in meters, or metres or whatever.

It depends on what you are used to. If you grew up on imperial, then that is easier.

Disagree. I did grow with imperial, I am 'Murican!. Did use it in my shop for 30+ years, but then switched to metric when I started building my shop around Festool (German tools). I've made far fewer mistakes (quick! what's 5 5/16 - 2 1/4????) since switching.

But we are far off topic here. You can't argue with me on what I say is easier for myself!

A. 7-9/16ths
B. I would never argue with you on what is easiest for you. But, “generally, usually, most often“ the law of primacy says whatever you learn first gives you the quickest recognition. Some people pass that by and adapt. If you read a couple other threads, you’ll find I’m a big fan of adapting…

Bzzzzzt!!!!!!

3 1/16"...... thanks for proving my point!

Funny thing is when you fly over Russia it's all in metric all of a sudden, then you fly over western Europe and its imperial.

I don't doubt some have ability to do the conversions on the fly, but I never needed to and therefore aren't good at it. Familarity is not necessarily the same as easy, at least in my book. Even just a socket set is annoying enough, and having to carry two sets of similar sizes with, even more so. (That's why I also have Metrinch sockets and spanners, also pulls stripped bolts)

But in saying that, with metric scaling there is simply no conversion at all, you just change the zeros which requires zero processing whatsoever and the number is the same. The worst that can happen is that you're a order of magnitude out, which is a noticeable size difference without math.

As fritter63 pointed out, the margin for error is way less, and because it's SI base it is also the reason NASA only uses metric. Like 1 Nm/s = 1W. Add earth gravity acceleration 9.81m/s² and I can already tell you how big to build a hydro power station. Too easy, even I can remember that.

And honestly the adhoc way imperial measurements came about, never really had science as it's main motivation, rather only building construction and trade. Honestly it still surprises me that most flying is still imperial, and still teaching it in school makes something simple, unnecessarily hard, and leaves some kids and development behind.

Sorry, I was adding, not subtracting. That doesn't prove your point, it only points out that I didn't read the freakin question! That was a brain fart, not a fraction addition error.

Unless, of course, your point was I have ADD and rush things. In which case, you are absolutely correct.

You are correct. Russia, N Korea AND China are all metric. And even in most of eastern Europe you go back to feet. Gravity acceleration is one of the few math formulas I think is easier in imperial. Instead of 9.81mps/s it's 32fps/s.

Again, I don't disagree that the base 10 system makes far better sense. I'm just saying it's not an easy conversion if you learned the other way. My generation wa supposed to be raised "bilingual" and then begin the change. But the great experiment failed and people didn't take to it. And we haven't even started talking about degrees vs radians. ALL of my navigation, bearing/distance, and course projection libraries are in radians. I have to convert from degrees, calculate, and convert back. No doubt it is a better way. The margin of error is not based on your units of measurement, it's based on your level of precision. Any accuracy can be matched

And ALMOST all of NASA is metric. The original Hubble team missed that memo.

We changed over to metric and survived.
I lived through the transition, In school I learned Imperial.. and out of school I had to change.

I still think of short distances in terms of feet , and even inches. I sort of interchange depends on what I am measuring I suppose.

But overall, best thing ever to get rid of stupid fractions.

The CT SS is 3mm, or maybe 2.88mm or 2.77 or 2.76 ?

or is it 3/140ths lol

 

[flowerlandfilms]

want an American truck, you get imperial measures

I thought I was buying a South African truck.

 

[CyberGus]

Somehow the people still want imperialism in their measures.

The metric system is as easy and as straight forward as the decimal system.

it seems to me the there are things the metric system is better for, and things imperial is better for

Again, I don't disagree that the base 10 system makes far better sense.

so, for the rest of the world, the CT is 200 cm wide

Possibilmente 201cm
