For the imperial system, pounds is used both as a measurement of mass and force. Another reason I hate it so much.
I'll convert the grams of hydrogen to Newtons, then convert that to pounds-force if you want.
And like I said, since all chemistry measuremtents are metric, converting it to Imperial causes problems anyways.
I completely agree with people being brainwashed to use it, I've gotten into arguments with so many teachers about the metric system. They all claim the Imperial system is easier, and makes more sense. Even though the base measurements in the Imperial system are derived from the metric system. And plus, everything in the metric system is based off powers of 10. You just have to memorize all the measurements in the Imperial system, you can't figure it out by knowing the prefixes and whatnot.
Sorry for the rant. If you can't tell, I despise the Imperial system.
