Convert watt-hour to erg
Please provide values below to convert watt-hour [W*h] to erg [erg], or Convert erg to watt-hour.
1 W*h = 36000000000 erg. To convert watt-hour to erg, multiply the value by 36000000000; to go the other way, divide by it (1 erg = 2.7778e-11 W*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 W*h = 36000000000 erg
- 1 erg = 2.7778e-11 W*h
- 10 W*h = 360000000000 erg
- 100 W*h = 3.6000e+12 erg
How to Convert Watt-Hour to Erg
1 W*h = 36000000000 erg
Example: convert 15 W*h to erg:
15 W*h = 15 × 36000000000 erg = 540000000000 erg

Watt-Hour
A watt-hour (W·h) is a unit of energy equal to the amount of energy transferred or used when one watt of power is sustained for one hour.
History/Origin
The watt-hour was established as a practical unit of energy measurement with the adoption of the International System of Units (SI) and has been used in electrical and energy industries to quantify energy consumption and storage since the 20th century.
Current Use
Watt-hours are commonly used to measure electrical energy consumption in household appliances, batteries, and energy storage systems, providing a convenient unit for billing, capacity ratings, and energy management.
Erg
The erg is a unit of energy in the centimeter-gram-second (CGS) system, defined as the amount of work done when a force of one dyne displaces an object by one centimeter.
History/Origin
The erg was introduced in the late 19th century as part of the CGS system of units, primarily used in physics to measure small amounts of energy before the adoption of the SI system.
Current Use
Today, the erg is largely obsolete and rarely used outside of specific scientific contexts, with the SI unit joule being the standard for energy measurement. It remains relevant in some fields like astrophysics and theoretical physics.
