Description

Joule (J)

The joule is the SI unit of energy, named after physicist James Prescott Joule. It represents the energy transferred when one newton of force moves an object one meter. Widely used in physics and engineering, 1 joule equals 1 watt-second or 0.239 calories. It is fundamental to understanding energy, work, and heat across scientific disciplines.

Watt-hour (Wh)

The watt-hour is a common unit of energy used to measure electrical power over time. One watt-hour equals 3,600 joules and is often used to describe the energy capacity of batteries and home appliances.
