Enter a value in million BTU below to convert to another unit of energy.

What Is a Million BTU?

A million BTU is a unit used to measure energy.

The million BTU is a US customary unit of energy. Million BTU can be abbreviated as MMBTU; for example, 1 million BTU can be written as 1 MMBTU.

How Much Is a Million BTU?

One million BTU is a measure of heat energy equal to 1,000,000 BTU, which are equal to the amount of heat energy required to increase the temperature of one pound of water one degree Fahrenheit.

How to Convert Million BTU

To convert million BTU to another unit of energy, you need to multiply the value by a conversion factor. A conversion factor is a numerical value used to change the units of a measurement without changing the value.[1]

You can find the conversion factors for million BTU in the conversion table below.

Then, multiply the energy measurement by the conversion factor to find the equivalent value in the desired unit of measurement.

million BTU × conversion factor = result

You can also use a calculator, such as one of the converters below, for the conversion.
