LPG Gas Unit Conversions
LPG energy content gas unit conversion is expressed in BTU per kg. LPG – Propane BTU per kg = 46,452 BTU per kg. Since 1kg of LPG = 1.96 L, then based on the above 1.96 x 23,700 BTU/L = 46,452 BTU. So, 1kg = 46,452 BTU per kg. Combining metric and imperial measures is not typical but it can be easily calculated.
Calculating the Stored Energy of a Pressurized Gas Vessel
