Convert Nanogray to Kilogray

Convert nanograys to kilograys by entering a value below.

1 nGy (nanograys) = 1e-12 kGy (kilograys)

How to Convert Nanograys to Kilograys

The nanogray and kilogray are both units of radiation dose. By definition, 1 kilogray equals exactly 1e12 nanograys. This means to convert nanograys to kilograys, you divide by 1e12.

Formula

kilograys = nanograys ÷ 1e12

Step-by-Step Example

Convert 5 nGy to kilograys:

1
Convert 5 nGy to kilograys

We need to convert nanograys to kilograys

2
Apply the formula

Since 1 kGy = 1e12 nGy, divide by 1e12

5 ÷ 1e12 = 5e-12

Answer

5 nGy = 5e-12 kGy

About These Units

Nanogray (nGy)

A nanogray (nGy) equals 10⁻⁹ grays. Used in background radiation measurements and environmental monitoring. Natural background dose rate: 50-200 nGy/h from cosmic rays and terrestrial sources. Sensitive dosimeters measure in nGy.

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.
