How to Convert Btu Per Hour to Milliwatts

To convert a btu per hour measurement to a milliwatt measurement, multiply the power by the conversion ratio. One btu per hour is equal to 293.071 milliwatts, so use this simple formula to convert:

milliwatts = btu per hour × 293.071

The power in milliwatts is equal to the btu per hour multiplied by 293.071.

For example, here's how to convert 5 btu per hour to milliwatts using the formula above.
5 Btu/h = (5 × 293.071) = 1,465.355 mW

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

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.

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.
