I thought the conversion was exact. The latent heat of fusion of 1 pound of water at 0°C is 144 BTU. 144 BTU/lb * 2000 lb/ton / 24 hr is 12000 BTU/hr per ton e

- kens 3y agoNo, the latent heat of fusion is 143.6 BTU/pound, not 144. It's just a coincidence that the energy to raise water one °F ÷ the energy to melt ice is almost 144.
