How it's calculated
Result = value × (joules per from-unit) ÷ (joules per to-unit) 1 cal = 4.184 J · 1 kWh = 3.6 MJ · 1 BTU = 1055.05585262 J
Every energy unit goes through joules. The calorie here is the thermochemical calorie (4.184 J); a food Calorie is a kilocalorie. The BTU is the International Table value, and the US therm is 100 000 BTU (59 °F).
