Specific Heat Calculator
Specific heat capacity formula. The formula for specific heat looks like this: c = frac {Q} {m Delta T} c = mΔT Q. Q is the amount of supplied or subtracted heat (in joules), m is the mass of the sample, and ΔT is the difference between the initial and final temperatures. Heat capacity is measured in J/ (kg·K).
