Convert Kilogray to Nanogray

Convert kilograys to nanograys by entering a value below.

1 kGy (kilograys) = 1e12 nGy (nanograys)

How to Convert Kilograys to Nanograys

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

Formula

nanograys = kilograys × 1e12

Step-by-Step Example

Convert 5 kGy to nanograys:

1
Convert 5 kGy to nanograys

We need to convert kilograys to nanograys

2
Apply the formula

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

5 × 1e12 = 5e12

Answer

5 kGy = 5e12 nGy

About These Units

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.

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.
