What is a microjoule used for?

A microjoule quantifies very small energy amounts such as pulse energy in lasers, energy in small capacitors, and mechanical work in micro-scale sensors.

When should I use attojoules?

Attojoules are used to express extremely small energies relevant at atomic or molecular levels, including single-photon energies and quantum device applications.

What is the exact conversion rate between microjoules and attojoules?

One microjoule equals one trillion attojoules (1 µJ = 1,000,000,000,000 aJ).
