About this free energy unit converter tool
Convert joules, kilojoules, food kilocalories and kilowatt-hours. Calculators answer a defined arithmetic question using the values you supply. Keep units and currencies consistent, choose the correct starting amount and inspect the assumptions before using a result. Estimates do not replace a lender quotation, an official tax rate, a medical assessment or a jurisdiction-specific deadline rule.
A practical example
A concrete example uses energy: 1; input unit: kWh. The result is J: 3600000 kJ: 3600 kcal: 860.42065 kWh: 1.
Before you rely on the result
Results use floating-point arithmetic and are rounded to six decimal places. Confirm units and required precision before using the result. kcal uses the thermochemical calorie definition.
