Specific Heat Capacity Converter
Specific heat capacity is the energy needed to raise one kilogram of a substance by one degree. The SI unit is the joule per kilogram kelvin. Because a Celsius degree and a kelvin are the same size, per-°C and per-K figures are numerically identical. Water is the reference at about 4,186 J/(kg·K), or exactly 1 BTU per pound per °F.

Multiply the number of joules per kilogram kelvin by 0.001 to get kilojoules per kilogram kelvin. How this is calculated
About specific heat capacity conversion
Specific Heat Capacity conversion is commonly needed when heating and cooling loads, thermal storage, and materials selection. A kelvin and a Celsius degree are the same size, so per-K and per-°C figures never need converting.
