Convert Nanogray to Microgray

Type the number of nanograys that you wish to convert to micrograys.

1 nGy (nanograys) = 0.001 μGy (micrograys)

How to Convert Nanograys to Micrograys

The nanogray and microgray are both units of radiation dose. By definition, 1 microgray equals exactly 1000 nanograys. This means to convert nanograys to micrograys, you divide by 1000.

Formula

micrograys = nanograys ÷ 1000

Step-by-Step Example

Convert 5 nGy to micrograys:

1
Convert 5 nGy to micrograys

We need to convert nanograys to micrograys

2
Apply the formula

Since 1 μGy = 1000 nGy, divide by 1000

5 ÷ 1000 = 0.005

Answer

5 nGy = 0.005 μGy

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.

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.
