When does the world go metric...

[300bar]

or can some one please explain the differance between cft.and liters.
so how does a 80cft tank compares to a xx lt.tank.
as I understand it Lt. is the water content of a tank,and cft is the compresed air content.

Plaese make a list,
70 cft
72 cft
80 cft
100 cft
and so on.

thanx

Right, so you can not convert the ltrs to cft without knowing the pressure.

Someone correct me if I'm wrong, but I think you first convert the cft into free L by multiplying by 28.3, and then divide it by the tank's rated pressure in bar (1 bar = 14.5 psi).

So if you an 80 cft tank rated at 3000 psi, then that's equivalent to 3000/14.5 = 207 bar. Now take the 80 * 28.3 = 2264 and divide it by 207 = 10.9. Or you would just call it 11 L tank.

'The world' has already gone metric. It's the pesky USA that refuses to fall in line. :shakehead

I remember when I was in grade school, they had us learn the metric system since we would eventually convert to it. That was almost fifty years ago and we still haven't. Maybe if we really want to reach international markets, we could follow the standards most of them use.

We do! Just not in everything in own country. I can remember during the Carter era we had speed limit signs etc. in both KPH and MPH. Today our vehicles are mostly built with metric. The manufacturers list the specs on their websites in standard and metric. Our scientists work in the metric system.

I am taking lunch while screwing around on the net, but working in standard using cad drawings to mount the front axle and brackets, of my rockcrawler. Doh! I wish it was metric measurements. Fractions; who are we kidding? Puhleasssse...I can move decimel places in my head to convert easily.

We up here in the "Great White North" had metric shoved down our throats in the late 70's.It remains a sore spot for me still, However I still use whichever system suits me! I believe the conversion you are looking for is "cubic metres" not litres. You'll have to do the math yourself one foot=30cm or .3m....BRANT

They still had that dream alive when I was in grade school, and that was only about 30 something years ago! (must have been an evil ploy by the nuns to make us learn metric!)

1 ft^3 = 28.316847l = 0.028317 m^3

All units of volume!

My only problem with meteric is that 20 degrees will never sound like a nice day out!

Allow me to rephrase the question in a way that will answer the question I would ask.... if an al80 is the standard tank throughout the US, Canada, and the Caribbean, what would the equivilent tank be in Europe?
