Some popular units for comparing energy include British Thermal Units (Btu), barrels of oil equivalent, metric tons of oil equivalent, metric tons of coal equivalent, and terajoules. In the United States, the Btu, a measure of heat energy, is the most commonly used unit for comparing fuels.
What are three examples of units used for energy?
Common Units of energy
- Barrel of oil.
- Joule (J)
- Kilowatt-hour (kWh)
- Kilowatt (kW)
- Megajoule (MJ)
- Megawatt (MW)

What units make up a BTU?
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 are the four units of energy?
units of energy are joule,dyne,unit or kilowatt hour, horsepower..
What is Joule formula?
In equation form: work (joules) = force (newtons) x distance (meters), where a joule is the unit of work, as defined in the following paragraph. In symbols: W = F x d. In practical terms, even a small force can do a lot of work if it is exerted over a long distance.
What is the unit of Joule?
What are 4 types of coal?
Coal is classified into four main types, or ranks: anthracite, bituminous, subbituminous, and lignite. The ranking depends on the types and amounts of carbon the coal contains and on the amount of heat energy the coal can produce.
How many MMbtu is a ton of coal?
There are 2000 lb in a short ton so that makes (12000 * 2000) = 24 MMbtu of energy in a short ton of NYMEX coal.
How much energy is in a ton of coal?
Activity: One ton of coal can produce 2,500 kilowatt hours (kwh) of electricity. One ton equals 2,000 pounds (lbs.).

Are higher BTUs better?
A heater with a higher BTU rating is more powerful — that is, it has a higher heat output — than one with a low BTU rating. It can do more to raise the temperature in your room each hour, so you can either heat a room more quickly or heat a larger space.
How do you use BTU?
A Btu is the amount of heat necessary to raise the temperature of 1 pound (0.45 kilograms) of water one degree Fahrenheit (0.56 degrees Celsius). One Btu equals 1,055 joules. In heating and cooling terms, one ton equals 12,000 Btu. A typical window air conditioner might be rated at 10,000 Btu.
