A metric Tonne is a little more than an American Ton as well. Had a neighbor who owned a Canadian gravel company, had to watch which one was on the order form.

The conversion isn't as straight forward until you understand you have to factor the rated fill pressure.
 
Hi all,

If you look at the specs, an XS Scuba 80 aluminum tank has 77.4cu ft/11.1 liters - Luxfer-Cylinders-Aluminum — XS Scuba

An XS Scuba 80 Steel tank has 81.7cu ft/10.2 liters - Steel Cylinders — XS Scuba

So the aluminum tank has less cu ft, but higher liters.
Whereas the steel tank has more cu ft, but less liters.

Why is this? Does this mean the aluminum tank has greater air capacity?
Steel doesn't jam to 3000 psi. It's 2400 in most cases.
 
All the steel tanks I have used have been 232 bar or 3300 psi. LP (low pressure) steel tanks aren't really a thing outside the US
