Convert Milligray to Kilogray
Type the number of milligrays that you wish to convert to kilograys.
How to Convert Milligrays to Kilograys
The milligray and kilogray are both units of radiation dose. By definition, 1 kilogray equals exactly 1000000 milligrays. This means to convert milligrays to kilograys, you divide by 1000000.
Formula
Step-by-Step Example
Convert 5 mGy to kilograys:
We need to convert milligrays to kilograys
Since 1 kGy = 1000000 mGy, divide by 1000000
5 ÷ 1000000 = 5e-6
5 mGy = 5e-6 kGy

About These Units
Milligray (mGy)
A milligray (mGy) equals 0.001 gray or 0.1 rad. Common medical imaging doses: CT scan 10-30 mGy, mammogram 2-3 mGy, fluoroscopy 20-50 mGy. Diagnostic reference levels often specified in mGy.
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.
