WebMar 4, 2024 · The mathematical formula below proves how 1 ton of cooling equates to 12,000 Btuh. (2,000 lb ice) x (144 Btu/lb) ÷ (24 hours) = 12,000 Btuh. so, 1 ton of cooling = 12,000 Btuh or 200 Btu/min. Note: The latent heat of fusion for ice is 144 Btu/lb, which means that 144 Btu are absorbed for each pound of ice that is melted to water.
