How to Convert Megawatt-hours to British Thermal Units

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

Since one megawatt-hour is equal to 3,412,141.633128 british thermal units, you can use this simple formula to convert:

british thermal units = megawatt-hours × 3,412,141.633128

The energy in british thermal units is equal to the megawatt-hours multiplied by 3,412,141.633128.

For example, here's how to convert 5 megawatt-hours to british thermal units using the formula above.
5 MWh = (5 × 3,412,141.633128) = 17,060,708.16564 BTU

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


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]

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.
