Convert Nanogray to Microsievert

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

1 nGy (nanograys) = 0.001 μSv (microsieverts)

How to Convert Nanograys to Microsieverts

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

Formula

microsieverts = nanograys ÷ 1000

Step-by-Step Example

Convert 5 nGy to microsieverts:

1
Convert 5 nGy to microsieverts

We need to convert nanograys to microsieverts

2
Apply the formula

Since 1 μSv = 1000 nGy, divide by 1000

5 ÷ 1000 = 0.005

Answer

5 nGy = 0.005 μSv

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.

Microsievert (μSv)

A microsievert (μSv) equals 0.001 mSv or 0.1 mrem. Common exposures: dental X-ray ~5 μSv, chest X-ray 20 μSv, transatlantic flight 40-80 μSv, banana (K-40) 0.1 μSv. Most radiation meters display μSv/h for environmental monitoring.
