How to Convert British Thermal Units to Megawatt-hours

To convert a british thermal unit measurement to a megawatt-hour measurement, multiply the energy by the conversion ratio.

Since one british thermal unit is equal to 2.9307E-7 megawatt-hours, you can use this simple formula to convert:

megawatt-hours = british thermal units × 2.9307E-7

The energy in megawatt-hours is equal to the british thermal units multiplied by 2.9307E-7.

For example, here's how to convert 5,000,000 british thermal units to megawatt-hours using the formula above.
5,000,000 BTU = (5,000,000 × 2.9307E-7) = 1.465355 MWh

British thermal units and megawatt-hours are both units used to measure energy. Keep reading to learn more about each unit of measure.

British Thermal Units

British thermal units are a measure of heat energy. Specifically, one british thermal unit is equal to the amount of heat energy required to increase the temperature of one pound of water one degree Fahrenheit. They are often used as a way to rate the energy heat producing appliances such furnaces, and to price heating fuels such as natural gas.

The british thermal unit is a US customary unit of energy. British thermal units can be abbreviated as BTU; for example, 1 british thermal unit can be written as 1 BTU.


A megawatt-hour is a measure of electrical energy equal to one megawatt, or 1,000,000 watts, of power over a one hour period. Megawatt-hours are a measure of electrical work performed over a period of time, and are often used as a way of measuring energy usage by electric companies.

Megawatt-hours are usually abbreviated as MWh, although the formally adopted expression is MW·h. The abbreviation MW h is also sometimes used. For example, 1 megawatt-hour can be written as 1 MWh, 1 MW·h, or 1 MW h.

In formal expressions, the centered dot (·) or space is used to separate units used to indicate multiplication in an expression and to avoid conflicting prefixes being misinterpreted as a unit symbol.[1]
