1 quad = 1 × 10¹⁵ Btu

Show the working
  1. 1 quad = 1e15 Btu
  2. 1 × 1e15 = 1e15 Btu

How to convert quads to british thermal units

1 quad = 1 × 10¹⁵ Btu, so multiply by 1 to go from quads (10¹⁵ Btu) to British thermal units (IT). Going the other way, 1 Btu = 1 × 10⁻¹⁵ quad.

Btu = quad × 1
quad = Btu × 1

Worked example:

1 quad = 1e15 Btu
5 × 1e15 = 5e15 Btu
