Comparing Gas vs Electric Heating

1 therm of natural gas delivers the heating energy equivalent of approximately 29.3 kWh of electric resistance heat. Comparing fuel costs per therm against electricity per kWh allows homeowners to optimize utility expenses.

Understanding Energy Units & Converting kWh to Therm

When managing household utility bills or analyzing thermodynamic HVAC systems, navigating different energy units can be confusing. Electric power utilities meter consumption in kilowatt-hours (kWh), while natural gas providers bill in therms or CCF. Using an automated kwh to therm calculator enables homeowners, engineers, and facility managers to assess energy efficiency accurately.

Kilowatt-Hour (kWh)

A standard metric unit of energy equal to 3,600,000 Joules (3.6 MJ). Represents consuming 1,000 watts of electrical power continuously for one hour.

US Therm

A non-metric unit of heat energy commonly defined as exactly 100,000 British Thermal Units (BTU), or approximately 105.5 megajoules.

The Mathematical kWh to Therm Conversion Formula

The exact physical relationship between kilowatt-hours and therms is governed by:

Therms = kWh × 0.03412957
kWh = Therms × 29.30011

Frequently Asked Questions

How to convert kWh to therm?

To convert kWh to therm, multiply the kilowatt-hour value by 0.03412957 (or divide by 29.30011). For example, 100 kWh × 0.03412957 = 3.41 therms.

What are common energy units used in utility bills?

The primary energy units used in household utility metering are kilowatt-hours (kWh) for electric power, therms (or CCF - hundreds of cubic feet) for natural gas, and British Thermal Units (BTU) for heating and HVAC equipment ratings.
