\text{BTU/lb}

BTU per pound

Specific energy Specific latent heatexact by definition

One BTU per pound, equal to about 2326 J/kg. It is the North American process and fuel unit, and it appears throughout older combustion and heating literature.

1 $\text{BTU/lb}$ (Specific energy)	2,326 $\text{J/kg}$
1 $\text{BTU/lb}$ (Specific latent heat)	2,326 $\text{J/kg}$

As a unit of specific latent heat

The BTU per pound is the customary US unit of latent heat, exactly 2326 J/kg using the International Table BTU. The factor follows exactly from the IT BTU of 1055.05585262 J divided by the pound of 0.45359237 kg, so it is exact by definition. Water's latent heat of fusion is about 144 BTU/lb and of vaporisation about 970 BTU/lb at atmospheric pressure.
