## Watt-hours

The watt-hour is a measure of electrical energy equal to one watt of power over a one hour period.

Watt-hours are usually abbreviated as *Wh*, although the formally adopted expression is *W·h*. The abbreviation *W h* is also sometimes used. For example, 1 watt-hour can be written as 1 Wh, 1 W·h, or 1 W 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]}

## 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.

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.
