The joule per kilogram-Kelvin is the SI derived unit of specific heat, expressing the energy needed to raise one kilogram by one Kelvin.
It was adopted as the SI unit alongside the development of calorimetry, providing a standard way to compare material heating capacity.
Measurement system: International System of Units (SI). SI equivalent: Base SI specific heat unit.
