  1. 1 Btu = 1e-15 quad
  2. 1 × 1e-15 = 1e-15 quad

How to convert british thermal units to quads

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

quad = Btu × 1
Btu = quad × 1

Worked example:

1 Btu = 1e-15 quad
5 × 1e-15 = 5e-15 quad
