How to Convert Btu per Hour to Milliwatts

To convert a measurement in btu per hour to a measurement in milliwatts, multiply the power by the following conversion ratio: 293.071 milliwatts/btu per hour.

Since one btu per hour is equal to 293.071 milliwatts, you can use this simple formula to convert:

milliwatts = btu per hour × 293.071

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

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

How Many Milliwatts Are in One Btu per Hour?

There are 293.071 milliwatts in one btu per hour, which is why we use this value in the formula above.

1 Btu/h = 293.071 mW

What Are 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 the expressions of units, the slash, or solidus (/), is used to express a change in one or more units relative to a change in one or more other units.

What Is a Milliwatt?

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 thousandths, or 10-3. Milliwatts can be abbreviated as mW; for example, 1 milliwatt can be written as 1 mW.
