The thermochemical calorie is exactly 4.184 J by definition of the International Organization for Standardization (ISO). [4] The thermochemical Btu is calculated by converting from grams to pounds and from Celsius to Fahrenheit. [5] 59 °F (15.0 °C) ≈1,054.80 [6] Used for American natural gas pricing. [3] 60 °F (15.6 °C) ≈1,054.68 [7]
12,000.00 Btu IT /h 2,593.90 ft⋅lbf/s A ton of refrigeration ( TR or TOR ), also called a refrigeration ton ( RT ), is a unit of power used in some countries (especially in North America) to describe the heat-extraction capacity of refrigeration and air conditioning equipment.
The BTU was originally defined so that the average specific heat capacity of water would be 1 BTU/lb⋅°F. [19] Note the value's similarity to that of the calorie - 4187 J/kg⋅°C ≈ 4184 J/kg⋅°C (~.07%) - as they are essentially measuring the same energy, using water as a basis reference, scaled to their systems' respective lbs and °F ...

The energy content of biofuel is the chemical energy contained in a given biofuel, measured per unit mass of that fuel, as specific energy, or per unit of volume of the fuel, as energy density.
The beaked hazelnut is named for its fruit, which is a nut enclosed in a husk with a tubular extension 2–4 cm (3 ⁄ 4 – 1 + 1 ⁄ 2 in) long that resembles a beak. Tiny filaments protrude from the husk and may stick into, and irritate, skin that contacts them. The spherical nuts are small and surrounded by a hard shell.
The energy content of ethanol is 76,100 BTU/US gal (5.89 kilowatt-hours per litre), compared to 114,100 BTU/US gal (8.83 kWh/L) for gasoline. (see chart above) A flex-fuel vehicle will experience about 76% of the fuel mileage MPG when using E85 (85% ethanol) products as compared to 100% gasoline.
Corylus avellana, the common hazel, is a species of flowering plant in the birch family Betulaceae.The shrubs usually grow 3–8 metres (10–26 feet) tall. The nut is round, in contrast to the longer filbert nut.
