Convert Rads to Kilograys
Convert Rads (rad) to Kilograys (kGy) instantly and accurately.
Conversion Formula
kGy = rad × 1.000000000e-5
About Rads
The rad (rad) equals exactly 0.01 Gy = 100 erg/g. The pre-SI unit of absorbed dose, defined by the ICRU in 1953, still widely used in the US in radiation therapy (cGy = rad numerically), radiation biology, and NRC regulations. Whole-body 50% lethal dose (LD50) for humans ~350-450 rad. 1 rad = 0.01 Gy = 1 cGy.
About Kilograys
The kilogray (kGy) equals 10³ Gy and is the standard unit for radiation processing. Food irradiation: 1-10 kGy for insect disinfestation and sprout inhibition; medical device sterilisation standard dose is 25 kGy (ISO 11137); polymer crosslinking and cable insulation curing use 50-200 kGy. 1 kGy = 10³ Gy = 10⁵ rad.
