One kilojoule per kilogram, a thousand joules per kilogram. It is the working unit of thermodynamic and process calculations, where enthalpies and heats of reaction land conveniently in the hundreds to thousands.

As a unit of specific latent heat

The kilojoule per kilogram is a thousand joules per kilogram and the usual form in steam and refrigerant tables. Water takes 334 kJ/kg to melt and about 2257 kJ/kg to boil at atmospheric pressure, a ratio of nearly seven to one that shapes everything from ice storage to steam heating. The factor of 1000 is exact, being a decimal prefix.
