How to Convert Microwatts to Btu Per Hour

To convert a microwatt measurement to a btu per hour measurement, multiply the power by the conversion ratio. One microwatt is equal to 3.4121E-6 btu per hour, so use this simple formula to convert:

btu per hour = microwatts × 3.4121E-6

The power in btu per hour is equal to the microwatts multiplied by 3.4121E-6.

For example, here's how to convert 5 microwatts to btu per hour using the formula above.
5 µW = (5 × 3.4121E-6) = 1.7061E-5 Btu/h

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


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

The microwatt is a multiple of the watt, which is the SI derived unit for power. In the metric system, "micro" is the prefix for 10-6. Microwatts can be abbreviated as µW, for example 1 microwatt can be written as 1 µW.

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.
