How to Convert Milliwatts to Btu Per Hour

To convert a milliwatt measurement to a btu per hour measurement, multiply the power by the conversion ratio. One milliwatt is equal to 0.003412 btu per hour, so use this simple formula to convert:

btu per hour = milliwatts × 0.003412

The power in btu per hour is equal to the milliwatts multiplied by 0.003412.

For example, here's how to convert 500 milliwatts to btu per hour using the formula above.
500 mW = (500 × 0.003412) = 1.706071 Btu/h

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

Milliwatts

One milliwatt is the power equal to 1/1,000 of a watt, or the energy consumption at a rate of 1/1,000 of a joule per second.

The milliwatt is a multiple of the watt, which is the SI derived unit for power. In the metric system, "milli" is the prefix for 10-3. Milliwatts can be abbreviated as mW, for example 1 milliwatt can be written as 1 mW.

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.
