How to Convert Roentgens to Picosieverts
The roentgen and picosievert are both units of radiation dose. By definition, 1 roentgen equals exactly 8770000000 picosieverts. This means to convert roentgens to picosieverts, you multiply by 8770000000.
Formula
Step-by-Step Example
Convert 5 R to picosieverts:
We need to convert roentgens to picosieverts
Since 1 R = 8770000000 pSv, multiply by 8770000000
5 × 8770000000 = 43850000000
5 R = 43850000000 pSv

About These Units
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.
Picosievert (pSv)
A picosievert (pSv) equals 10⁻¹² sieverts. Theoretical scale for extremely low doses, radiation shielding calculations, and cosmic ray flux measurements. One microsievert equals one million picosieverts.
