What is a therm (US)?

A therm (US) is a non-SI unit of heat energy equal to 100,000 British thermal units, commonly used in the United States for measuring natural gas and heating energy.

What does a megaton (Mton) measure?

A megaton (Mton) is a very large unit of energy used to express explosive yields equal to the energy released by one million metric tons of TNT.

Why convert therm (US) to megaton (Mton)?

This conversion helps translate common natural gas energy measurements into contexts involving extremely large energy releases, such as nuclear tests or large asteroid impacts.
