Convert Rem to Nanosievert

Enter the number of rem that you want to convert to nanosieverts.

1 rem (rem) = 10000000 nSv (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

nanosieverts = rem × 10000000

Step-by-Step Example

Convert 5 rem to nanosieverts:

1
Convert 5 rem to nanosieverts

We need to convert rem to nanosieverts

2
Apply the formula

Since 1 rem = 10000000 nSv, multiply by 10000000

5 × 10000000 = 50000000

Answer

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.
