Frequently asked questions
What is the source unit in this conversion?
The source unit is the kWh (kWh). A kilowatt-hour is 3.6 million joules.
What is the destination unit in this conversion?
The destination unit is the Yoctojoule (yJ). Yoctojoule is 1e-24 joule units.
How do I convert kWh to Yoctojoule?
Multiply the kWh value by 3.6e+30. For example, 10 kWh × 3.6e+30 = 3.6e+31 yJ.
Is the kWh to Yoctojoule conversion exact?
Yes. Both units belong to the same engineering measurement family (energy), so the ratio between them is a fixed, defined value rather than a measured approximation.
Where is this conversion commonly used?
It's used whenever a value expressed in kWh needs to be compared with, or reported in, Yoctojoule, such as in engineering, scientific, or industrial calculations.
Can I convert Yoctojoule back to kWh?
Yes. Multiply the Yoctojoule value by 0 to get kWh.

About this conversion
This page converts kWh (kWh) to Yoctojoule (yJ) within the engineering converter.
A kilowatt-hour is 3.6 million joules. Yoctojoule is 1e-24 joule units.
The formula is yJ = kWh × 3.6e+30, based on each unit's fixed relationship to the energy base unit.
The conversion is exact, since it relies on a fixed numerical ratio between the two units rather than a measured or approximate value.
