About These Units

Kilojoule (kJ)

A kilojoule (kJ) equals 1,000 joules or approximately 239 calories. Kilojoules measure food energy on nutrition labels in Australia, Europe, and many countries. An average adult needs 8,400-10,000 kJ daily. One kJ equals approximately 0.239 kcal.

Kiloelectronvolt (keV)

A kiloelectronvolt (keV) equals 1,000 electronvolts. KeV measures X-ray energy (medical X-rays: 20-150 keV), electron microscope beam energy, and radiation dosimetry. Gamma rays from nuclear decay often have energies in keV to MeV range.
