Convert attojoule to Btu (th)
Please provide values below to convert attojoule [aJ] to Btu (th) [Btu (th)], or Convert Btu (th) to attojoule.
1 aJ = 9.4845e-22 Btu (th). To convert attojoule to Btu (th), multiply the value by 9.4845e-22; to go the other way, divide by it (1 Btu (th) = 1.0544e+21 aJ). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 aJ = 9.4845e-22 Btu (th)
- 1 Btu (th) = 1.0544e+21 aJ
- 10 aJ = 9.4845e-21 Btu (th)
- 100 aJ = 9.4845e-20 Btu (th)
How to Convert Attojoule to Btu (Th)

Attojoule
An attojoule (aJ) is a unit of energy equal to 10^-18 joules.
History/Origin
The attojoule was introduced as part of the SI prefixes to measure extremely small amounts of energy, particularly in fields like nanotechnology and quantum physics, as the need to quantify very tiny energy scales grew.
Current Use
The attojoule is used in scientific research to measure minute energy quantities, such as in nanotechnology, quantum computing, and molecular biology, where energies involved are extremely small.
Btu (Th)
The Btu (th), or British thermal unit (th), is a unit of energy used primarily in the United States to measure heat content, equivalent to the amount of heat needed to raise the temperature of one pound of water by one degree Fahrenheit.
History/Origin
The Btu (th) originated from the British thermal unit, a traditional unit of heat in the British Imperial system, and has been used historically in heating, cooling, and energy industries to quantify energy content and heat transfer.
Current Use
Today, the Btu (th) is mainly used in the energy sector, particularly in heating and cooling systems, natural gas billing, and energy content measurement, especially within the United States.
