How to Convert Btu Per Hour to Watts

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

Since one btu per hour is equal to 0.293071 watts, you can use this simple formula to convert:

watts = btu per hour × 0.293071

The power in watts is equal to the btu per hour multiplied by 0.293071.

For example, here's how to convert 5 btu per hour to watts using the formula above.
5 Btu/h = (5 × 0.293071) = 1.465355 W

Btu Per Hour

One BTU per hour is equal to one british thermal unit, or the energy needed to heat one pound of water 1 °F, for one hour.

The btu per hour is a US customary unit of power. Btu per hour can be abbreviated as Btu/h; for example, 1 btu per hour can be written as 1 Btu/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.
