One kilowatt-hour
3,600,000 J, 3.6 MJ, about 860.42065 kcal, and about 3,412.14163 BTU.
Convert scientific, electrical, food, and mechanical energy units through a shared joule-based engine.
Energy is the capacity to do work. Every conversion first converts the source value to joules and then converts joules to the target unit.
A kilowatt is power, while a kilowatt-hour is energy: 1 kWh is the energy used by a 1 kW device operating for one hour.
J = kWh × 3,600,000J = cal × 4.184J = kcal × 4,184J = BTU × 1,055.055852623,600,000 J, 3.6 MJ, about 860.42065 kcal, and about 3,412.14163 BTU.
Exactly 418.4 kJ.
Exactly 3,600 J.
The International Table BTU equals 1,055.05585262 J.
The joule is the SI unit and the converter's canonical base.
The converter's cal unit is the thermochemical calorie: 1 cal = 4.184 J exactly. Its separate kcal unit is 1,000 thermochemical calories, or 4,184 J; a food Calorie commonly means a kilocalorie. International Table calories use a different factor and are not a selectable unit here.
BTU here means International Table BTU. Foot-pound is a mechanical energy unit.
Power measures the rate of energy use. Energy accumulates over time: a 1 kW device operated for 1 hour uses 1 kWh.
1,000 joules.
3,600,000 joules.
kW measures power; kWh measures energy.
One kcal equals 1,000 of this converter's thermochemical calories (cal).
A food Calorie commonly means one kilocalorie (kcal), or 1,000 of this converter's thermochemical calories (cal).
Approximately 3,412.14163 International Table BTU.
The International Table BTU, equal to 1,055.05585262 joules.
Yes. Negative energy values are mathematically meaningful in some contexts and are supported.
