RapidTables.com | In 1908, the "international" definitions were defined, with Siemens' definition being adopted as the international watt. 1 watt ≈ 0.0002843 tons . And, here is the key. The power P in BTUs per hour (BTU/hr) is equal to 3.412141633 times the power P in watts (W):. A ton of refrigeration is approximately equal to 12,000 BTU/h or 3.5 kW. BTU per hour (BTU/h) to refrigeration tons (RT) conversion calculator and how to convert. Use this page to learn how to convert between watts and tons of refrigeration. watt or ton of refrigeration The SI derived unit for power is the watt. One watt, the International System of Units derived unit of power, is equal to approximately 3.41214 Btu/h.

Current use: The British thermal unit per hour is not a widely used unit. History/origin: The ton of refrigeration originated around the 1880s during the transition from stored natural ice to mechanical refrigeration. Ton of refrigeration. Definition: The British thermal unit per hour (symbol: Btu/h) is a United States customary system unit of power.

Therefore, there is no reason cooling cannot be measured in kWh and IT energy consumption in tons! The savvy data center manager will be able to do just that. BTU/hr to watts conversion calculator How to convert watts to BTU/hr.


These were used until 1948 when the General Conference on Weights and Measures re-defined the watt to absolute units, using only mass, time, and length.

Please provide values below to convert Btu (IT)/hour [Btu/h] to ton (refrigeration), or vice versa.

A ton of refrigeration is approximately equal to 12,000 BTU/h or 3.5 kW. Definition: A ton of refrigeration (TR) is a unit of power.

›› Quick conversion chart of Btu/s to ton.

Enter the power in BTU/hr and press the Convert button: One refrigeration ton is equal to 12000 BTUs per hour: One BTU per hour is equal to 8.33333×10-5 refrigeration ton: So the power P in refrigeration tons (RT) is equal to the power P in BTUs per hour (BTU/hr) divided by 12000: P(RT) = 10000 BTU/hr / 12000 = 0.83333 RT, © The ton is more often a unit of mass. This eventually led to the founding of the American Society of Refrigerating Engineers in 1904. One refrigeration ton is equal to 12000 BTUs per hour: 1 RT = 12000 BTU/hr. 1 Btu/h = 8.33333E-5 ton (refrigeration)1 ton (refrigeration) = 12000 Btu/h, Example: convert 15 Btu/h to ton (refrigeration):15 Btu/h = 15 × 8.33333E-5 ton (refrigeration) = 0.00125 ton (refrigeration), Btu (IT)/hour to Horsepower (550 Ft*lbf/s). The watt as a unit of power should not be confused with its energy counterpart, the watt-hour (and all its multiples/submultiples). History/origin: The watt is named after James Watt, a Scottish inventor. It is defined as the power required to melt or freeze 2000 pounds, also known as one short ton, of ice per day. It is defined as 1 joule per second and is used to quantify the rate of energy transfer. One watt, the International System of Units derived unit of power, is equal to approximately 3.41214 Btu/h.
This unit is often abbreviated as simply "Btu," which is the same abbreviation used for British thermal units, a measurement of heat. About |
