Convert roentgens to microroentgens by entering a value below.
How to Convert Roentgens to Microroentgens
The roentgen and microroentgen are both units of radiation dose. By definition, 1 roentgen equals exactly 1000000 microroentgens. This means to convert roentgens to microroentgens, you multiply by 1000000.
Formula
Step-by-Step Example
Convert 5 R to microroentgens:
We need to convert roentgens to microroentgens
Since 1 R = 1000000 μR, multiply by 1000000
5 × 1000000 = 5000000
5 R = 5000000 μR

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.
Microroentgen (μR)
A microroentgen (μR) equals 0.001 mR. Used in environmental radiation monitoring, radon measurements, and low-level contamination surveys. Natural background: 10-20 μR/h typical. Sensitive ion chambers measure in μR/h.
