Conversion Factors
Conversion Factors: The following
factors enable you to convert between different energy units. 1 therm = 100,000 btu's
BTU = 252.5 c or 0.252 C
Kilowatt Hour (KWH) =
3413 BTU
Horsepower-hours = 1.341 KWH
Propane, gallon =
92,500 BTU*
Gasoline, gallon = 125,000 BTU*
Kerosene, gallon =
135,000 BTU*
Diesel oil, gallon = 138,700
BTU*
Fuel Oil, gallon No. 5 =
148, 000 BTU*
*This is an approximate value
typically used for this conversion. Because these are average values, the exact BTU content varies with type and source, it
is important to contact the supplier when accuracy is important.
