How many types of British Thermal Units are there???

Actually there aren't ANY kind(s)... because Americans are the only nation left using them...

If I remember correctly... in my (British) physics lessons... we changed to metric in about 1966... first cgs (ergs anyone??) and then mks (SI)

So, perhaps it's time to rename them American Thermal units??

Interesting. The world's largest cosumer seems to be out of step with the rest of the world. Why am I not suprised?

Never mind, the Americans have two different inches to make up for it, 25.4mm for most uses and 1000/39.37 = 25.4000508...mm
for survey work

A BTU is the amount of heat required to raise the temperature of one pound of water one degree fahrenheit at sea level.
