Convert Roentgen to Picosievert

Convert roentgens to picosieverts by entering a value below.

1 R (roentgens) = 8770000000 pSv (picosieverts)

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

picosieverts = roentgens × 8770000000

Step-by-Step Example

Convert 5 R to picosieverts:

1
Convert 5 R to picosieverts

We need to convert roentgens to picosieverts

2
Apply the formula

Since 1 R = 8770000000 pSv, multiply by 8770000000

5 × 8770000000 = 43850000000

Answer

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.
