kJ (Metric), energy

The joule (symbol: J) is the SI unit of energy, which is defined as the potential to do work. The joule has base units of kg·m²/s² = N·m. The base unit conversion can be remembered using the equation E = mc2, where E is in joules, m is in kilograms, and c is the speed of light in meters per second.
