What is the calorific value for LPG?

The calorific value of LPG can be worked out using the following calculations:

• 1 Tonne = 1000kg or 1969 litres, therefore 1kg = 1.969 litres
• 1 Litre of propane = 7.08 kWh (kilowatt hours) or 24000 BTU/h
• 1kg of propane = 14.019 kWh (kilowatt hours) or 47300 BTU/h

To convert from m³ or ft³ into litres use the following calculations:

• To convert m³ of vapour to litres of liquid; multiply by 3.85
• to convert ft³ of vapour to litres; multiply by 0.1034
