What is a microjoule?

A microjoule (µJ) is one millionth of a joule and is used to measure very small amounts of energy in scientific and engineering fields.

How is a kilowatt-second related to a joule?

A kilowatt-second is equal to one kilojoule, representing one kilowatt of power applied for one second.

When should I use this conversion?

Use this conversion to relate small energy measurements in microjoules to practical energy values expressed over time in kilowatt-seconds, common in laser experiments and power electronics.
