Convert Millirad to Kilogray
Type the number of millirads that you wish to convert to kilograys.
How to Convert Millirads to Kilograys
The millirad and kilogray are both units of radiation dose. By definition, 1 kilogray equals exactly 100000000 millirads. This means to convert millirads to kilograys, you divide by 100000000.
Formula
Step-by-Step Example
Convert 5 mrad to kilograys:
We need to convert millirads to kilograys
Since 1 kGy = 100000000 mrad, divide by 100000000
5 ÷ 100000000 = 5e-8
5 mrad = 5e-8 kGy

About These Units
Millirad (mrad)
A millirad (mrad) equals 0.001 rad or 10 μGy. Used in medical dosimetry: dental bitewing 0.5-2 mrad, chest X-ray 10-20 mrad. Provides convenient scale for diagnostic imaging dose specifications.
Kilogray (kGy)
A kilogray (kGy) equals 1,000 grays. Used for industrial irradiation: food preservation 1-10 kGy, medical device sterilization 25-50 kGy, cross-linking polymers 50-200 kGy. Far above any biological survivability.
