Specific latent heatexact by definition
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.
