1 quad = 6.58514067819 × 10³⁶ eV

Show the working
  1. 1 quad = 6.58514067819e36 eV
  2. 1 × 6.58514067819e36 = 6.58514067819e36 eV

How to convert quads to electronvolts

1 quad = 6.58514067819 × 10³⁶ eV, so multiply by 6.58514067819 to go from quads (10¹⁵ Btu) to electronvolts. Going the other way, 1 eV = 1.51857044347 × 10⁻³⁷ quad.

eV = quad × 6.58514067819
quad = eV × 1.51857044347

Worked example:

1 quad = 6.58514067819e36 eV
5 × 6.58514067819e36 = 3.2925703391e37 eV
