Convert Microroentgen to Milliroentgen
Input the number of microroentgens you want to convert to milliroentgens.
How to Convert Microroentgens to Milliroentgens
The microroentgen and milliroentgen are both units of radiation dose. By definition, 1 milliroentgen equals exactly 1000 microroentgens. This means to convert microroentgens to milliroentgens, you divide by 1000.
Formula
Step-by-Step Example
Convert 5 μR to milliroentgens:
We need to convert microroentgens to milliroentgens
Since 1 mR = 1000 μR, divide by 1000
5 ÷ 1000 = 0.005
5 μR = 0.005 mR

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.
Milliroentgen (mR)
A milliroentgen (mR) equals 0.001 roentgen. Radiation survey meters often display mR/h for monitoring X-ray and gamma fields. Natural background: 10-20 mR/year. Typical survey meter range: 0-1000 mR/h.
