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 5 milliwatts to btu per hour using the formula above.
5 mW = (5 × 0.003412) = 0.017061 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.
