How do you find kcal in physics?
Enter the necessary data and then click on the active text above for the quantity you wish to calculate . For a mass m = gm = kg. with specific heat c = cal/gm°C = joule/gm°C, initial temperature Ti = °C = K = °F. and final temperature Tf = °C = K = °F, Q = calories = kcal = x 10^ calories . Q = joules = x 10^ joules.
