Convert Rem to Nanosievert
Enter the number of rem that you want to convert to nanosieverts.
How to Convert Rem to Nanosieverts
The rem and nanosievert are both units of radiation dose. By definition, 1 rem equals exactly 10000000 nanosieverts. This means to convert rem to nanosieverts, you multiply by 10000000.
Formula
Step-by-Step Example
Convert 5 rem to nanosieverts:
We need to convert rem to nanosieverts
Since 1 rem = 10000000 nSv, multiply by 10000000
5 × 10000000 = 50000000
5 rem = 50000000 nSv

About These Units
Rem (rem)
The rem (Roentgen Equivalent Man) is the traditional unit of equivalent dose. One sievert = 100 rem exactly. Still used in US nuclear industry and regulations. Annual occupational limit: 5 rem/year. Natural background: 0.3 rem/year. Acute 450 rem ≈ LD50.
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.
