# Heat capacity

Heat capacity (C) also called thermal capacity, is the amount of heat needed to raise the temperature of an object through 1 °C, either at constant pressure or at constant volume and without inducing chemical changes or a change of phase. Numerically it is equal to the product of the mass (m) of the object and its specific heat (c).

$C=m\cdot c=\dfrac{\Delta Q}{\Delta T}$

Heat capacity is measured in joules per kelvin (J/K) (SI units).
