Convert Sievert to Nanosievert
Enter the number of sieverts that you want to convert to nanosieverts.
How to Convert Sieverts to Nanosieverts
The sievert and nanosievert are both units of radiation dose. By definition, 1 sievert equals exactly 1000000000 nanosieverts. This means to convert sieverts to nanosieverts, you multiply by 1000000000.
Formula
Step-by-Step Example
Convert 5 Sv to nanosieverts:
We need to convert sieverts to nanosieverts
Since 1 Sv = 1000000000 nSv, multiply by 1000000000
5 × 1000000000 = 5000000000
5 Sv = 5000000000 nSv

About These Units
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.
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.
