Kilogram-force Meters to Kilowatt-hours (kgf⋅m to kWh)

1 kilogram-force meter equals 0.000002724069444 kilowatt-hours (rounded).

1 kilogram-force meter = 0.000002724069444 kilowatt-hours

How to convert kilogram-force meters to kilowatt-hours

To convert kilogram-force meters to kilowatt-hours, multiply the number of kilogram-force meters by 0.000002724069444. The factor is rounded to 10 significant digits. To go the other way, multiply kilowatt-hours by 367,097.8367 (rounded).

kilowatt-hours = kilogram-force meters × 0.000002724069444

Example: 10 kilogram-force meters = 0.00002724069444 kilowatt-hours.

The 'calorie' on food labels is really a kilocalorie. The thermochemical calorie (4.184 J) is used here unless marked IT.

About these units

Kilogram-force Meter (kgf⋅m)

CGS & old metricHistorical unit (no longer in standard use)

Exactly 9.80665 joules, the work of lifting one kilogram by one meter on Earth. Common in older engineering and for torque in Asia.

Kilogram-force meter is the work done when a force of one kilogram-force acts through one meter, a unit of the old gravitational metric system of engineers. Since a kilogram-force is 9.80665 newtons, it equals 9.80665 joules, using the conventional standard gravity adopted in 1901.

Engineers favored it because weights in kilograms could be multiplied directly by heights in meters to give lifting work. The same combination is also used for torque, where NIST lists it against the newton meter with the same factor of 9.80665, and it is sometimes written as kilopond meter.

The kilogram-force was never part of the International System of Units, and the newton replaced it after 1948. Even so, older motor and tool specifications, especially from Asian and European sources, still quote torque in kgf m, and dividing by about ten gives a rough figure in newton meters.

1 kilogram-force meter = 9.80665 joules (exactly).

Kilowatt-hour (kWh)

Metric (SI)Current unit

3.6 million joules, the energy used by a 1,000-watt appliance in an hour. The billing unit for household electricity.

Before it was a line on every power bill, the kilowatt-hour had a British nickname: the Board of Trade unit, abbreviated B.T.U. after the government body that regulated the electricity industry until 1942, when the Ministry of Power took over. In India it is still often called simply a unit, and a million of them, written MU, is a gigawatt-hour.

A kilowatt-hour is the energy of a 1 kW device running for an hour, which is 3.6 MJ, or about 3,412 British thermal units. A 100 W television watched for 10 hours uses one, and boiling a liter of water in an electric kettle takes about 0.1. In 2020 the average US household used 893 kWh a month, an average continuous draw of about 1.22 kW.

Utilities multiply the kilowatt-hours consumed by a price per kWh, and larger customers may also pay for peak demand. One common error is writing kW/h, which would mean kilowatts per hour, a rate of change of power, not energy.

1 kilowatt-hour = 3,600,000 joules (exactly).
