The quantity of heat required to raise the temperature of one pound of water one degree Fahrenheit at a particular temperature (there are several different precise definitions) and a pressure of one atmosphere
a unit of heat equal to the amount of heat required to raise one pound of water one degree Fahrenheit at one atmosphere pressure; equivalent to 251 997 calories
The quantity of heat required to increase the temperature of one pound of water one degree Fahrenheit (The Recycler's Lexicon: A Glossary of Contemporary Terms and Acronyms, Resource Recycling Inc , 1995)
Measurement unit for heat It is the amount of energy required to raise the temperature of one pound of water one degree from 62 to 63 degrees Fahrenheit One Btu is equal to 252 calories and to 1055 joules
The standard unit for measuring quantity of heat energy It is the amount of heat energy necessary to raise the temperature of one pound of water one degree Fahrenheit
The most basic energy measurement unit of all fuels, defined as the amount of heat required to raise the temperature of one pound of water one degree Fahrenheit
(BTU) A standard unit for measuring the quantity of heat needed to raise the temperature of 1 pound of water by 1 degree Fahrenheit at or near 39 2 degrees Fahrenheit
(BTU)-a unit of heat used to describe the capacity of boilers and furnaces One BTU equals the amount of heat required to raise the temperature of one pound of water one degree Farenheit at sea level
(BTU) (heat) (meas) The amount of heat required to raise the temperature of one pound of water one degree FAHRENHEIT under stated conditions of temperature and pressure (e g sea level) In the Imperial system of measurements (as compared to the International System, SI, of measurements) it is the standard unit for measuring quantity of HEAT ENERGY One Btu is about equal to the heat released from burning one kitchen match It is also equal to 1,055 joules, the SI unit of measurement Generally abbreviated as Btu F - British thermal unit S - unidad termica britanica
One British thermal unit, or Btu, is roughly equivalent to burning one kitchen match The standard of measurement used for measuring the amount of heat required to raise the temperature of one pound of water by one degree (Fahrenheit) That may not sound like much, but a typical home consumes about 100 million Btus per year Approximately one-half for the total is used for space heating
