2. Ton of refrigeration - Wikipedia

   en.wikipedia.org/wiki/Ton_of_refrigeration

   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.

3. British thermal unit - Wikipedia

   en.wikipedia.org/wiki/British_thermal_unit

   The Btu should not be confused with the Board of Trade Unit (BTU), an obsolete UK synonym for kilowatt hour (1 kW⋅h or 3,412 Btu). The Btu is often used to express the conversion-efficiency of heat into electrical energy in power plants. Figures are quoted in terms of the quantity of heat in Btu required to generate 1 kW⋅h of electrical energy.

4. Heat of combustion - Wikipedia

   en.wikipedia.org/wiki/Heat_of_combustion

   The heating value (or energy value or calorific value) of a substance, usually a fuel or food (see food energy), is the amount of heat released during the combustion of a specified amount of it.

5. Specific heat capacity - Wikipedia

   en.wikipedia.org/wiki/Specific_heat_capacity

   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 ...

6. Gasoline gallon equivalent - Wikipedia

   en.wikipedia.org/wiki/Gasoline_gallon_equivalent

   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. Simple calculations of the BTU values of the ...

7. Energy content of biofuel - Wikipedia

   en.wikipedia.org/wiki/Energy_content_of_biofuel

   The table below includes entries for popular substances already used for their energy, or being discussed for such use. The second column shows specific energy, the energy content in megajoules per unit of mass in kilograms, useful in understanding the energy that can be extracted from the fuel.

9. Talk:British thermal unit - Wikipedia

   en.wikipedia.org/wiki/Talk:British_thermal_unit

   As of right now the unit conversion template gives different values for 1,000 British thermal units per pound (2,300 kJ/kg) and 1,000 British thermal units per pound (2,300 kJ/kg) while describing both units as "British Thermal Units". Is there some method to the madness or does the code need fixing?
