# Kilocalorie (th) to all other Energy conversions

## Kilocalorie–TH

A thermochemical kilocalorie (th kcal) is a decimal multiple of a thermochemical calorie, which is an outdated non-SI metric unit of energy. In most fields its use has been replaced by, the joule, the SI unit of energy. However, it remains a commonly used unit for energies in the field of chemistry. 1 th calorie = 4.184 J as defined in the ISO standard ISO 31-4. By definition, the small calorie or gram calorie approximates the energy needed to increase the temperature of 1 gram of water by 1 °C at standard atmospheric pressure (101.325 kPa).
