 From: kilowatt To: Btu (IT)/hour

### Kilowatt

Definition: A kilowatt (symbol: kw) is a unit of power in the International System of Units (SI). The base unit of the kilowatt is the watt, which was named after Scottish inventor James Watt. As is consistent with SI units, the prefix kilo- means that a kilowatt equals one thousand watts or one thousand joules per second.

History/origin: The base unit of the kilowatt is the watt, which was named after a Scottish inventor named James Watt. This was first proposed in 1882 by Sir Charles William Siemens, an engineer and entrepreneur, who suggested the use of Watt's name as a unit of power. He defined the unit within the system of units being used at the time, and his definition was adopted in 1908.

Current use: Kilowatts are used worldwide, typically to express the output power of engines and the power of electric motors, tools, machines, and heaters. Electricity used by a home is typically measured in kilowatt hours, or kWh, meaning 1000 watts being applied over a period of one hour. Megawatt or gigawatt hours may be used in larger buildings or for industrial applications.

### British thermal unit per hour

Definition: The British thermal unit per hour (symbol: Btu/h) is a United States customary system unit of power. This unit is often abbreviated as simply "Btu," which is the same abbreviation used for British thermal units, a measurement of heat. One watt, the International System of Units derived unit of power, is equal to approximately 3.41214 Btu/h.

History/origin: The British thermal unit per hour is based on the British thermal unit (symbol: Btu or BTU), a traditional United States customary unit of heat, where heat is a type of energy transfer in which energy moves from a hotter to a colder substance. The BTU is specifically defined as the amount of heat required to increase the temperature of one pound of water by one °F. It has a number of different definitions all of which equate to approximately 1,055 joules.

Current use: The British thermal unit per hour is not a widely used unit. Multiples of the watt hour, often the kilowatt hour, are more frequently used than Btu/h, even in the United States.
