How to convert joules to quads

1 J = 9.47817120313 × 10⁻¹⁹ quad, so multiply by 9.47817120313 to go from joules (watt-seconds) to quads (10¹⁵ Btu). Going the other way, 1 quad = 1.05505585262 × 10¹⁸ J.

quad = J × 9.47817120313
J = quad × 1.05505585262

Worked example:

1 J = 9.47817120313e-19 quad
5 × 9.47817120313e-19 = 4.73908560157e-18 quad
