How to Convert Watts to Kilocalories Per Hour

To convert a watt measurement to a kilocalorie per hour measurement, multiply the power by the conversion ratio. One watt is equal to 0.860421 kilocalories per hour, so use this simple formula to convert:

kilocalories per hour = watts × 0.860421

The power in kilocalories per hour is equal to the watts multiplied by 0.860421.

For example, here's how to convert 5 watts to kilocalories per hour using the formula above.
5 W = (5 × 0.860421) = 4.302104 kcal/h

Watts and kilocalories per hour are both units used to measure power. Keep reading to learn more about each unit of measure.

Watts

One watt is the power equal to the rate of energy of one joule per second in an electrical circuit. One watt is also equal to the power produced in a circuit with a voltage potential of one volt with a current of one amp.

The watt is the SI derived unit for power in the metric system. Watts can be abbreviated as W, for example 1 watt can be written as 1 W.

Watt's Law states the relationship between power, current, and voltage. Using Watt's Law, it's possible to express the power in watts as an expression using current and voltage.

PW = IA × VV

The power in watts is equal to the current in amperes times the potential difference in volts.

Combining this with Ohm's Law, it's also possible to express the power in watts using resistance in addition to volts and amps.

Kilocalories Per Hour

One kilocalorie per hour is equal to one kilocalorie, or 1,000 times the energy needed to heat one gram of water 1 °C, for one hour.

Kilocalories per hour can be abbreviated as kcal/h, for example 1 kilocalorie per hour can be written as 1 kcal/h.
