To convert a measurement in watts to a measurement in kilocalories per hour, multiply the power by the following conversion ratio: 0.860421 kilocalories per hour/watt.

Since one watt is equal to 0.860421 kilocalories per hour, you can use this simple formula to convert:

kilocalories per hour = watts × 0.860421

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

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

How Many Kilocalories per Hour Are in a Watt?

There are 0.860421 kilocalories per hour in a watt, which is why we use this value in the formula above.

1 W = 0.860421 kcal/h

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

What Is a Watt?

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.

What Are 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 the expressions of units, the slash, or solidus (/), is used to express a change in one or more units relative to a change in one or more other units.
