Heating Fuels - Cost Comparing

Cost comparison formulas for heating fuels like Natural Gas, Propane LP Gas, Fuel Oil and Electricity.

Average cost comparison formulas for heating fuels:


C e = p e (100000 Btu) / (3412 Btu/ kWh )                  (1)


C e = electricity cost per 100000 Btu

p e = electricity price per kWh

Natural Gas

C ng = p ng (100000 Btu) / (1028 Btu/ft3 )                 (2)


C ng = natural gas cost per 100000 Btu

p ng = natural gas price per cubic ft.

Propane LP Gas (Liquid Propane Gas)

C lp = p lp (100000 Btu) / (91333 Btu/ gallon )                  (3)


C lp = propane gas cost per 100000 Btu

p lp = propane price per gallon

Fuel Oil

C fo = p fo (100000 Btu) / (140000 Btu/ gallon )                (4)


C fo = fuel oil cost per 100000 Btu

p fo = fuel oil price per gallon
