What is Btu used to measure?
heat content
A British thermal unit (Btu) is a measure of the heat content of fuels or energy sources. It is the quantity of heat required to raise the temperature of one pound of liquid water by 1 degree Fahrenheit at the temperature that water has its greatest density (approximately 39 degrees Fahrenheit).
What does Btu stand for how does a scientist define it?
The British thermal unit (BTU or Btu) is a unit of heat; it is defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. It is also part of the United States customary units. Heat is now known to be equivalent to energy.
What is Btu in agriculture?
Direct agricultural fuel consumption can be calculated by dividing annual fuel expenditure amounts by the price of each fuel product. This chart shows agriculture’s annual direct and indirect energy use, measured in trillion British thermal units, or Btu.
Is Btu power or energy?
The British Thermal Unit (BTU or Btu) is commonly used to describe the energy content of fuels and the power of heating and cooling systems. One BTU is the amount of energy required to raise the temperature of one pound of water by one degree Fahrenheit.
What is BTU reading?
BTU’s are a unit of measurement equivalent to the amount of heat required to increase the temperature of one pound of water by 1 degree Fahrenheit. BTU is an abbreviation for British Thermal Unit and has been used since the late 17th century.

What percentage of energy is used for agriculture?
In 2016, the agricultural sector consumed 1,872 trillion Btu of energy, accounting for about 1.9 percent of total U.S. primary energy consumption.
How is thermal energy used in agriculture?
Agricultural activities such as heating greenhouses, melting beeswax, evaporating milk, drying grains, making fruit wines, distillation, pickling, sterilizing meat processing equipment and drying produce all require medium range temperatures, while aquaponics and soil warming can utilize lower temperatures.
Are higher BTUs better?
A measure of an air conditioner’s power is its BTU rating. BTUs are the energy used to remove heat from a room. Therefore, the more BTUs an air conditioner unit has, the better equipped it is to cool a larger space.
What is BTU in natural gas?
Natural Gas has 1,030 BTUs per cubic foot. 135 Cubic feet equals the heat content of one gallon of oil. Kerosene has 131,890 BTUs per gallon.

What is the acronym of BTU in pressure?
Amount of heat required to raise 1 pound of water 1 degree Fahrenheit (from 59.50 to 60.50 F), measured at standard atmospheric pressure.
Are BTU still used?
The BTU is most often used as a measure of power (as BTU/hr or BTUH) in the power, steam generation, heating and air conditioning industries, It is still used in metric English-speaking countries (such as Canada), and remains the standard unit of classification for air conditioning units manufactured and sold in many …
When was BTU first used?
The term first came to popular attention in the year 1847, when James Prescott Joule fleshed out a number of closely related concepts in a lecture called On Matter, Living Force, and Heat.
What are five ways in which energy is used in agriculture?
Modern agriculture requires an energy input at all stages of agricultural production such as direct use of energy in farm machinery, water management, irrigation, cultivation and harvesting. Post-harvest energy use includes energy for food processing, storage and in transport to markets.
