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 = 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.
One calorie is 4.184 J. One kilocalorie, commonly called a food Calorie, is 1,000 calories or 4,184 J.
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.
1,000 calories.
A nutrition Calorie usually means one kilocalorie, or 1,000 small calories.
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.
