Convert Nanosievert to Sievert
Type the number of nanosieverts that you wish to convert to sieverts.
How to Convert Nanosieverts to Sieverts
The nanosievert and sievert are both units of radiation dose. By definition, 1 sievert equals exactly 1000000000 nanosieverts. This means to convert nanosieverts to sieverts, you divide by 1000000000.
Formula
Step-by-Step Example
Convert 5 nSv to sieverts:
We need to convert nanosieverts to sieverts
Since 1 Sv = 1000000000 nSv, divide by 1000000000
5 ÷ 1000000000 = 5e-9
5 nSv = 5e-9 Sv

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.
Sievert (Sv)
The sievert (Sv) is the SI unit of equivalent dose, measuring biological effect of radiation exposure. Accounts for radiation type via quality factors. 1 Sv = significant health risk, 4-5 Sv = 50% fatality (LD50). Acute exposure above 0.5 Sv causes radiation sickness.
