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.

Kilocalorie (thermochemical) (kcal)

One kilocalorie equals 1,000 calories or approximately 4,184 joules. It is the standard unit for measuring food energy and is often abbreviated as 'Calorie' (with a capital C) on food labels.
