Therms to Quads Converter

Convert therms (100,000 Btu) (thm) to quads (10¹⁵ Btu) (quad), 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 thm = 1 × 10⁻¹⁰ quad

Show the working
  1. 1 thm = 1e-10 quad
  2. 1 × 1e-10 = 1e-10 quad

How to convert therms to quads

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

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

Worked example:

1 thm = 1e-10 quad
5 × 1e-10 = 5e-10 quad
