Electric Equivalent Formula:
From: | To: |
Definition: This calculator converts gas consumption (in therms) to its electrical equivalent (in kWh) using a conversion factor.
Purpose: It helps compare energy usage between gas and electric appliances or estimate electrical needs when switching from gas to electric.
The calculator uses the formula:
Where:
Explanation: The gas consumption is multiplied by the conversion factor to determine the equivalent amount of electricity needed to produce the same amount of energy.
Details: This conversion helps in energy planning, cost comparisons between gas and electric systems, and when transitioning from gas to electric appliances.
Tips: Enter the gas consumption in therms and the conversion factor (default 29.3 kWh/therm). All values must be > 0.
Q1: What is a therm?
A: A therm is a unit of heat energy equal to 100,000 British Thermal Units (BTUs), commonly used to measure natural gas.
Q2: Why is the default conversion factor 29.3?
A: 29.3 kWh/therm is the standard conversion based on the energy content of natural gas, though this can vary slightly by region.
Q3: When would I change the conversion factor?
A: Adjust if your local utility provides a different conversion rate or if converting other gas types (like propane).
Q4: How do I find my gas consumption in therms?
A: Check your gas bill - consumption is typically listed in therms or CCF (1 CCF ≈ 1.037 therms).
Q5: Does this account for appliance efficiency?
A: No, this is a direct energy conversion. Actual electrical needs may vary based on appliance efficiency differences.
