What does millijoule measure?

Millijoule (mJ) is an SI derived unit measuring very small amounts of energy such as pulse energies from lasers and small electronic events.

Why convert millijoule to Btu (IT)?

Converting millijoule to Btu (IT) helps relate small-scale energy measurements to heat energy units used in thermodynamic engineering and fuel analysis.

Are the conversion results always easy to interpret?

Since millijoules are very small, the converted values in Btu (IT) can be very tiny decimal numbers which may require scaling for practical interpretation.
