Do you want to convert milliwatts to btu per hour?

## 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.
