Convert Microgray to Kilogray

Convert micrograys to kilograys by entering a value below.

1 μGy (micrograys) = 1e-9 kGy (kilograys)

How to Convert Micrograys to Kilograys

The microgray and kilogray are both units of radiation dose. By definition, 1 kilogray equals exactly 1000000000 micrograys. This means to convert micrograys to kilograys, you divide by 1000000000.

Formula

kilograys = micrograys ÷ 1000000000

Step-by-Step Example

Convert 5 μGy to kilograys:

1
Convert 5 μGy to kilograys

We need to convert micrograys to kilograys

2
Apply the formula

Since 1 kGy = 1000000000 μGy, divide by 1000000000

5 ÷ 1000000000 = 5e-9

Answer

5 μGy = 5e-9 kGy

About These Units

Microgray (μGy)

A microgray (μGy) equals 0.001 mGy or 0.1 mrad. Chest X-ray: ~20 μGy. Panoramic dental X-ray: 10-20 μGy. Used for specifying doses from diagnostic imaging with minimal exposure. One gray = one million micrograys.

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.
