# Convert Watts to Btu Per Hour

Enter the power in watts below to get the value converted to btu per hour.

Results in Btu Per Hour: 1,000 W = 3,412.14245 Btu/h

## How to Convert Watts to Btu Per Hour To convert a watt measurement to a btu per hour measurement, multiply the power by the conversion ratio. One watt is equal to 3.412142 btu per hour, so use this simple formula to convert:

btu per hour = watts × 3.412142

The power in btu per hour is equal to the watts multiplied by 3.412142.

For example, here's how to convert 5 watts to btu per hour using the formula above.
5 W = (5 × 3.412142) = 17.060712 Btu/h

## 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.

## 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.
