Combined electricity and gas energy calculator

Convert kWh and therms to a common heat-energy basis before adding them; gas volume is a different quantity.

Units

E_{\text{total}} = 3412 \times E_{e} + 100{,}000 \times G

Calculator

Enter the values you know and leave one box empty. Calculate finds the empty one, the result or any input.

Given

E_{\text{total}} = 3412 \times 24{,}000 + 100{,}000 \times 650 = 146{,}888{,}000

Symbol	Meaning	Unit
$E_{\text{total}}$	combined delivered energy	MJ
$E_{e}$	delivered electricity	kWh
$G$	delivered gas energy on the stated energy basis	MJ

Results are estimates for study and screening. Check the inputs, units and assumptions before you use them for design, billing or contract decisions.
