Convert Nanosievert to Roentgen

Type the number of nanosieverts that you wish to convert to roentgens.

1 nSv (nanosieverts) = 1.1402508552e-7 R (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

roentgens = nanosieverts ÷ 8770000

Step-by-Step Example

Convert 5 nSv to roentgens:

1
Convert 5 nSv to roentgens

We need to convert nanosieverts to roentgens

2
Apply the formula

Since 1 R = 8770000 nSv, divide by 8770000

5 ÷ 8770000 = 5.7012542759e-7

Answer

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.
