What is a gigajoule (GJ)?

A gigajoule (GJ) is an SI-derived energy unit equal to 10^9 joules, used to measure large amounts of thermal, mechanical, or chemical energy.

What is a microjoule (µJ)?

A microjoule (µJ) is one millionth of a joule (10⁻⁶ J), used to quantify very small energy amounts in scientific contexts like lasers and micro-scale devices.

Why convert gigajoules to microjoules?

This conversion bridges large-scale energy measurements to very fine energy units necessary in precision scientific and engineering applications.
