How to Convert Microroentgens to Rads
The microroentgen and rad are both units of radiation dose. 1 rad equals 1140250.8552 microroentgens. This means to convert microroentgens to rads, you divide by 1140250.8552.
Formula
Step-by-Step Example
Convert 5 μR to rads:
We need to convert microroentgens to rads
Since 1 rad = 1140250.8552 μR, divide by 1140250.8552
5 ÷ 1140250.8552 = 4.385e-6
5 μR = 4.385e-6 rad

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.
Rad (rad)
The rad (Radiation Absorbed Dose) is the traditional unit of absorbed dose. One gray = 100 rads exactly. One rad = 100 ergs/gram = 0.01 J/kg. Still used in US medical and nuclear industries. One rad = one centigray = one rem for gamma/X-rays.
