Convert Nanosievert to Millisievert
Type the number of nanosieverts that you wish to convert to millisieverts.
How to Convert Nanosieverts to Millisieverts
The nanosievert and millisievert are both units of radiation dose. By definition, 1 millisievert equals exactly 1000000 nanosieverts. This means to convert nanosieverts to millisieverts, you divide by 1000000.
Formula
Step-by-Step Example
Convert 5 nSv to millisieverts:
We need to convert nanosieverts to millisieverts
Since 1 mSv = 1000000 nSv, divide by 1000000
5 ÷ 1000000 = 5e-6
5 nSv = 5e-6 mSv

About These Units
Nanosievert (nSv)
A nanosievert (nSv) equals 10⁻⁹ sieverts or 0.001 μSv. Used for extremely low radiation levels in environmental monitoring, clean room specifications, and background radiation surveys. Natural background: ~200-300 nSv/h typical.
Millisievert (mSv)
A millisievert (mSv) equals 0.001 sieverts or 100 mrem. Natural background: 2-3 mSv/year. CT scan: 2-15 mSv. Annual occupational limit: 20-50 mSv (varies by country). Single dose above 100 mSv increases cancer risk slightly.
