Conversion Formula

mrad = kGy × 100000000

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.

About Millirads

The millirad (mrad) equals 10⁻³ rad = 10⁻⁵ Gy = 10 µGy. Older US health physics reports and NRC licence conditions quote occupational extremity doses in mrad; some film badge dosimetry reports still use mrad for historical continuity. 1 mrad = 10⁻³ rad = 10⁻⁵ Gy = 10 µGy.
