Understanding Therm to BTU Conversion

Quick Fact: 1 Therm = 100,000 BTU

What is a Therm?

A therm (thm) is a unit of heat energy equal to 100,000 BTUs. It's commonly used by natural gas companies to measure and bill for gas consumption. This unit makes billing more manageable as working with smaller numbers is more practical than using BTUs.

What is a BTU?

A British Thermal Unit (BTU) is defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit at sea level. It's widely used in the power, steam generation, heating, and air conditioning industries.

Conversion Formula:

BTU = Therms × 100,000

Common Uses

  • Natural gas billing and consumption measurement
  • HVAC system capacity calculations
  • Industrial process heating calculations
  • Energy efficiency assessments
