Gigajoules (GJ) to Megajoules (MJ) Converter

Understanding Gigajoules and Megajoules

A gigajoule (GJ) is a unit of energy equal to one billion (109) joules, while a megajoule (MJ) equals one million (106) joules. Therefore, 1 gigajoule = 1,000 megajoules.

Common Uses and Applications

Gigajoules are commonly used in large-scale energy measurements, such as industrial energy consumption and natural gas billing. Megajoules are often used in smaller-scale applications like food energy content and household energy consumption.

Quick Conversion Guide

To convert from gigajoules to megajoules, multiply the number of gigajoules by 1,000. For example: 5 GJ = 5,000 MJ 0.5 GJ = 500 MJ 10 GJ = 10,000 MJ
