Btu calculator for natural gas
Fuel Substitution Technical Guidance for Energy Efficiency
To calculate the life-cycle source energy savings, the fuel substitution calculator multiplies annual source energy factors from Table 2 and Table 3 (in BTU/kWh and BTU/Therm respectively, for electricity and natural gas) by the site energy savings for each year of the measure’s EUL.

BTU. You will also have to convert tons to pounds and then pounds to BTUs. To do this, use the following conversion factor: 1 ton = 2000 lbs. Then use the BTU value of the fuel to calculate BTUs. When calculating efficiency, your answers should range from 20-30% *You may use a calculator to determine efficiency for problems 4 – 6* 4.

Natural gas is reported in MMbtu in the spreadsheet calculator. The data for cogeneration steam production is recorded by the SJU power plant in pounds of steam. This figure must be converted into MMbtu in order to be entered into the CA-CP calculator. According to the Energy Star website, one pound of steam equals 1,194 Btu.
