Imperial for everything except weights + the milimetre is a very useful scale to use for a lot of mechnical things.

Fine by me. If our government still had balls you still all be the British Empire anyway

no no ... youd still be part of the roman empire

metric of course base 10 for teh win ! no weird base 12 systems

I measure in cubits. My speedometer displays kilo-cubits per hour.

Depending on what we are talking about, I use everything.

In LFS and driving it's Imperial (MPH, miles, miles per gallons, etc.)

At home, building something or whatever, again it's Imperial (feet, inches, pounds, etc.)

At work is where it gets confusing. I make and mold expanded foam plastic beads (like Styrofoam, but that is a brand name. I work with polypropylene and Polyethylene). We expand plastic pellets into foam with a pressurized reactor vessel up to 650 psi. In the molding press we use bar. And then to confuse matters even more, I work in the Engineering and Research department, so we have some pilot equipment that is 1/5th to 1/10th the size of our production equipment. We just got a new expansion reactor that has a gauge readout of megapascals and the pressure source reading in pascals. Our ovens are also all over the place some reading in F and some in C.

It's funny to hear the production molders say, "Wow, I thought the reactors were hotter than that. 155 degrees isn't that hot, our oven is at 175 degrees and we're in it all the time."

"Er, guys, your oven is reading in F and the reactors are in C! Go ahead and lay your hand on the reactor and tell me it's not hot!"

Quote from Hallen :

For the majority of 'Mericans, there is only one system. But we do call it "Imperial".
However, when you ask about feet, depending on who you talk to, you might get the question of which "feet"? US Survey foot, or International foot. They are different. illepall
Then we could get into the Texas Vara. A unit of measurements that is exactly 1/3 of 100 feet. Talk about a pain to use, lol.

Personally, I wish we would just switch to metric. I work in a field were measurements are critical and using multiple systems causes a bunch of errors and complications.

I use Imperial in LFS. I don't like KPH because there is too many ticks per unit so to speak. A MPH analog gauge is readable, a KPH guage is hard to read.

Thanks for all your explanation. The "texas vera" is really close to ten meters, I didnt know this unit !
Last year I worked in canada and pressure unit for tensile strength and other things about materials property made me crazy (kpsi...) ! I had no more numbers to compare : so hard. The thickness of materials in part of " were crazy too...
Anyway I use knots sometimes but only for plane. And since the fast car I had to switch form analog to numeric kph because analog kph is now nearly unreadable !

Metric here in Norway.

... USA USA USA. ...



wtf is wrong with CAPS on this forum..

Metric only.

We wouldnt roman empire fell, we more gave the countries back to people.

And what uses base 12? I cant think of any - only one comes to mind is 12 inches to a foot.

I use imperial even though I'm canadian. Guess that is what happens when you watch and play too much Na$car. I would also like to see the springs adjusted by pounds like in the Nascar Racing series, but thats a very minor detail. I know lower is softer and higher is stiffer thats all I need to know .

Metric, but I alternate between Bar & PSI.. so actually a mixture sometimes

Imperial (Mph, Hp & Torque)
&
Metric (Bar & KG)

same here
