btu per pound * pounds per gallon   OK, it sounds as if you know the value of fuel in oil btu per pound.Now find out how much a gallon of fuel oil weighs and multiply the bâ¦tu value x that weight in pounds and that is the value per gallon. Or simply, diesel fuel is #2 fuel oil which contains 140,000 btu per gallon.
How to convert tons to BTU/hr. One refrigeration ton is equal to 12000 BTUs per hour: 1 RT = 12000 BTU/hr. One BTU per hour is equal to 8.33333Ã10-5 refrigeration ton: 1 BTU/hr = 8.33333Ã10-5 RT. So the power P in BTUs per hour (BTU/hr) is equal to 12000 times the power P in refrigeration tons (RT):
