Convert horsepower hour to nanojoule
Please provide values below to convert horsepower hour [hp*h] to nanojoule [nJ], or Convert nanojoule to horsepower hour.
1 hp*h = 2.6845e+15 nJ. To convert horsepower hour to nanojoule, multiply the value by 2.6845e+15; to go the other way, divide by it (1 nJ = 3.7251e-16 hp*h). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 hp*h = 2.6845e+15 nJ
- 1 nJ = 3.7251e-16 hp*h
- 10 hp*h = 2.6845e+16 nJ
- 100 hp*h = 2.6845e+17 nJ
How to Convert Horsepower Hour to Nanojoule
1 hp*h = 2.68451954e+15 nJ
Example: convert 15 hp*h to nJ:
15 hp*h = 15 × 2.68451954e+15 nJ = 4.02677931e+16 nJ

Horsepower Hour
A horsepower hour (hp*h) is a unit of energy representing the amount of energy equivalent to one horsepower of power sustained over one hour of time.
History/Origin
The horsepower hour originated from the traditional unit of horsepower used to quantify engine power, combined with the hour to measure energy consumption or production over time. It has been used primarily in engineering and energy industries to express energy usage or capacity.
Current Use
Today, the horsepower hour is rarely used in practical applications, having been largely replaced by the joule and other SI units. However, it may still be referenced in historical data, legacy systems, or specific industries dealing with older measurement standards within the energy and mechanical sectors.
Nanojoule
A nanojoule (nJ) is a unit of energy equal to one billionth (10^-9) of a joule.
History/Origin
The nanojoule was introduced as part of the SI unit system to measure very small amounts of energy, especially in scientific and technological contexts, with its usage becoming more common with advancements in nanotechnology and micro-scale energy measurements.
Current Use
Nanojoules are used in fields such as electronics, nanotechnology, and physics to quantify small energy quantities, including in the measurement of energy consumption in micro- and nano-scale devices.
