Convert Nanosievert to Roentgen
Type the number of nanosieverts that you wish to convert to roentgens.
How to Convert Nanosieverts to Roentgens
The nanosievert and roentgen are both units of radiation dose. By definition, 1 roentgen equals exactly 8770000 nanosieverts. This means to convert nanosieverts to roentgens, you divide by 8770000.
Formula
Step-by-Step Example
Convert 5 nSv to roentgens:
We need to convert nanosieverts to roentgens
Since 1 R = 8770000 nSv, divide by 8770000
5 ÷ 8770000 = 5.7012542759e-7
5 nSv = 5.7012542759e-7 R

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.
Roentgen (R)
The roentgen (R) measures ionization produced by X-rays or gamma rays in air. One roentgen produces 2.58×10⁻⁴ C/kg of ionization. Approximately: 1 R ≈ 8.77 mGy or 0.877 rad in soft tissue. Named after Wilhelm Röntgen, discoverer of X-rays.
