Convert Microroentgen to Roentgen
Type the number of microroentgens that you wish to convert to roentgens.
How to Convert Microroentgens to Roentgens
The microroentgen and roentgen are both units of radiation dose. By definition, 1 roentgen equals exactly 1000000 microroentgens. This means to convert microroentgens to roentgens, you divide by 1000000.
Formula
Step-by-Step Example
Convert 5 μR to roentgens:
We need to convert microroentgens to roentgens
Since 1 R = 1000000 μR, divide by 1000000
5 ÷ 1000000 = 5e-6
5 μR = 5e-6 R

About These Units
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.
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.
