Convert Milligray to Kilogray

Type the number of milligrays that you wish to convert to kilograys.

1 mGy (milligrays) = 1e-6 kGy (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

kilograys = milligrays ÷ 1000000

Step-by-Step Example

Convert 5 mGy to kilograys:

1
Convert 5 mGy to kilograys

We need to convert milligrays to kilograys

2
Apply the formula

Since 1 kGy = 1000000 mGy, divide by 1000000

5 ÷ 1000000 = 5e-6

Answer

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.
