# Heating Fuels - Comparing Costs

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

Average cost comparison formulas for heating fuels:

### Electricity

*C _{e} = p_{e} (100000 Btu) / (3412 Btu/kWh) (1)*

*where *

*C _{e} = electricity cost per 100000 Btu*

*p _{e} = electricity price per kWh*

### Natural Gas

*C _{ng} = p_{ng} (100000 Btu) / (1028 Btu/ft^{3}) (2)*

*where *

*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)*

*where *

*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)*

*where *

*C _{fo} = fuel oil cost per 100000 Btu*

*p _{fo} = fuel oil price per gallon*
