Rads to Grays
1 rad = 0.01 Gy. Edit either value to convert instantly.
Conversion formula
Gy = rad × (0.01) × (1)1 rad = 0.01 Gy
rad (rad)
rad is a unit of absorbed dose: 1 rad = 0.01 Gy. Absorbed dose is deposited radiation energy per mass; 1 Gy = 1 J/kg. It is distinct from equivalent dose in sieverts.
