Quads to Therms Converter

Convert quads (10¹⁵ Btu) (quad) to therms (100,000 Btu) (thm), with the formula, a conversion table and exact factors.

Change the values and press Calculate to work out your own figures.

Enter an amount of energy, choose its unit and the unit you want. The answer is exact until it is shown, and the same value appears in every other unit.

A number, fraction (3/8), mixed number (1 1/2), scientific notation (2.5e6) or a simple sum such as 2*3.
The unit you want the answer in. Swap exchanges the two units.

  1. 1 quad = 10000000000 thm
  2. 1 × 10000000000 = 10000000000 thm

How to convert quads to therms

1 quad = 10,000,000,000 thm, so multiply by 10,000,000,000 to go from quads (10¹⁵ Btu) to therms (100,000 Btu). Going the other way, 1 thm = 1 × 10⁻¹⁰ quad.

thm = quad × 10,000,000,000
quad = thm × 1

Worked example:

1 quad = 10000000000 thm
5 × 10000000000 = 50000000000 thm
