1) Residual Fuel Oil - The liquid or semi-liquid, high-boiling fraction of residue from the distillation of crude oil.
- 1 Gallon (U.S.) = 3.785x10-3 m3 = 3.785 dm3 (liter)
- 1 ft3 = 0.02832 m3
- 1 barrel (US, oil) = 1.33 barrel (US, liq) = 5.61458 cu foot = 42 gallons (US, liq) = 158.9873 liter
- 1 lbm = 0.4536 kg
- 1 ton (short) = 2000 lbs = 907 kg
Btu - British Thermal Unit
The unit of heat in the imperial system - the BTU - is
- the amount of heat required to raise the temperature of one pound of water through 1oF (58.5oF - 59.5oF) at sea level (30 inches of mercury).
- 1 Btu (British thermal unit) = 1055.06 J = 107.6 kpm = 2.931 10-4 kWh = 0.252 kcal = 778.16 ft lbf = 1.0551010 ergs = 252 cal = 0.293 watt hours
An item using one kilowatt-hour of electricity will generate 3412 Btu.
