# Convert Kilowatt to Ton (refrigeration)

Please provide values below to convert kilowatt [kW] to ton (refrigeration), or *vice versa*.

### 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.

### Ton of refrigeration

**Definition:** A ton of refrigeration (TR) is a unit of power. It is defined as the power required to melt or freeze 2000 pounds, also known as one short ton, of ice per day. The ton is more often a unit of mass. A ton of refrigeration is approximately equal to 12,000 BTU/h or 3.5 kW.

**History/origin:** The ton of refrigeration originated around the 1880s during the transition from stored natural ice to mechanical refrigeration. It became an industry standard in 1903 when Thomas Shipley pushed for the formation of an industry association as well as for standardization of a number of equipment specifications. This eventually led to the founding of the American Society of Refrigerating Engineers in 1904.

**Current use:** The ton of refrigeration is mostly used in North America, specifically within the context of refrigeration and air conditioning equipment. It is often displayed alongside BTU/h specifications.
