1. The problem statement, all variables and given/known data I am just trying to convert Btu to J based on the heat capacity of water and it is not giving me the right answer. 2. Relevant equations 3. The attempt at a solution Btu = C(water) * m(1 lb) * dt(1 F) 1 lb = 0.454 kg 1 F = 9/5 K 1 Btu = 4.186 kJ/(kg*K) * .454 kg * (9/5)K = 3.42 kJ < should be 1054 J, what am I doing wrong?
