Specific Heat Converter

Convert specific heat capacity between J/(kg·K), cal/(g·°C) and BTU units.

Specific heat capacity — the energy needed to raise a unit mass by one degree — governs how much a substance heats or cools for a given energy input. Water's high value (about 4,186 J/(kg·K)) is why it's such a good coolant. Thermodynamics tables mix J/(kg·K), cal/(g·°C) and BTU/(lb·°F).

This converter translates any specific heat between joules per kilogram-kelvin, kilojoule, calorie-per-gram and BTU-per-pound units, so heat-load calculations line up regardless of the source's convention.
