Metalloids - also known as semimetals - are elements containing properties similar and midway between metals and nonmetals.
- 1 J/(kg K) = 2.389×10-4 kcal/(kg oC) = 2.389×10-4 Btu/lbmoF
- 1 kJ/kgK = 0.2389 kcal/(kg oC) = 0.2389 Btu/lbmoF = 103 J/(kg oC) = 1 J/(g oC)
- 1 Btu/lbmoF = 4186.8 J/ (kg K) = 1 kcal/(kg oC)
- 1 kcal/(kg oC) = 4186.8 J/ (kg K) = 1 Btu/lbmoF

Heating Energy
The energy required to heat a product can be calculated as
q = cp m dt (1)
where
q = heat required (kJ)
cp = specific heat (kJ/kg K, kJ/kg C°)
dt = temperature difference (K, C°)
Example - Heating Carbon Steel
2 kg of carbon steel is heated from 20 oC to 100 oC. The specific heat of carbon steel is 0.49 kJ/kgC° and the heat required can be calculated as
q = (0.49 kJ/kg oC) (2 kg) ((100 oC) - (20 oC))
= 78.4 (kJ)
