Convert watt-second to nanojoule
Please provide values below to convert watt-second [W*s] to nanojoule [nJ], or Convert nanojoule to watt-second.
1 W*s = 1000000000 nJ. To convert watt-second to nanojoule, multiply the value by 1000000000; to go the other way, divide by it (1 nJ = 1e-09 W*s). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 W*s = 1000000000 nJ
- 1 nJ = 1e-09 W*s
- 10 W*s = 10000000000 nJ
- 100 W*s = 100000000000 nJ
How to Convert Watt-Second to Nanojoule
1 W*s = 1000000000 nJ
Example: convert 15 W*s to nJ:
15 W*s = 15 × 1000000000 nJ = 15000000000 nJ

Watt-Second
A watt-second (W·s) is a unit of energy equivalent to one joule, representing the amount of energy transferred or converted when one watt of power is applied for one second.
History/Origin
The watt-second originated from the SI system of units, where the watt (W) is the SI derived unit of power, and the second (s) is the SI base unit of time. It has been used historically in physics and engineering to quantify energy, especially in contexts where energy transfer occurs over short durations.
Current Use
The watt-second is primarily used in scientific and engineering contexts to measure small amounts of energy, such as in electrical and mechanical systems. It is often replaced by the joule in modern applications but remains a recognized unit within the energy converter category.
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.
