How to Convert Kilocalories Per Hour to Watts

To convert a kilocalorie per hour measurement to a watt measurement, multiply the power by the conversion ratio.

Since one kilocalorie per hour is equal to 1.162222 watts, you can use this simple formula to convert:

watts = kilocalories per hour × 1.162222

The power in watts is equal to the kilocalories per hour multiplied by 1.162222.

For example, here's how to convert 5 kilocalories per hour to watts using the formula above.
5 kcal/h = (5 × 1.162222) = 5.81111 W

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

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.

In formal expressions, the slash, or solidus (/), is used to separate units used to indicate division in an expression.


One watt is the power equal to the rate of energy of one joule per second in an electrical circuit.[1] 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.
