FORMULAS & FACTS

BTU (British Thermal Unit) is the heat required to raise 1 pound of water 1°F

1 BTU = 252 cal = 0.252 kcal

1 cal = 4.187 Joules

BTU X 1.055 = Kilo Joules

BTU divided by 3,413 = Kilowatt (1 KW)

One gallon of 120°F (49°C) water weighs approximately 8.25 pounds.

Pounds x .45359 = Kilogram
