## Homework Statement

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.

## Homework Equations

## 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?
