Makila1A,
Yes, your answer was precisely what was asked for, but the figures he asked for are not useful in any meaningful way, unless one believes the speeds are identical, which they certainly are not.
I have always used the typical cruise speed divided into the fuel flow to arrive at the lb/nm, which is a great way to flight plan, because it also tells you how much payload is lost as range increases.
For the 76A 520 lb/hr divided by 140 knots yields 3.7 lb/nm, so a trip of 200 nm requires 3.7 lbs/nm times 200 nm = 740 lbs.
For a 332L2, 490 kg/hr divided by 145knots = 3.37kg/nm (7.46lb/nm)
I even do this in flight, as a quick way to check range, by using actual ground speed. Most pilots "think" in fuel flow, but the aircraft uses fuel per mile. The difference is quite meaningful, the 212 and 412 have virtually identical fuel flow, but the 412 is at least 15 knots faster, thus about 10 to 15% more range, a fact buried in oblivion if you think fuel flow.
