Convert Microsievert to Milliroentgen
Enter the number of microsieverts that you want to convert to milliroentgens.
How to Convert Microsieverts to Milliroentgens
The microsievert and milliroentgen are both units of radiation dose. 1 milliroentgen equals 8.77 microsieverts. This means to convert microsieverts to milliroentgens, you divide by 8.77.
Formula
Step-by-Step Example
Convert 5 μSv to milliroentgens:
We need to convert microsieverts to milliroentgens
Since 1 mR = 8.77 μSv, divide by 8.77
5 ÷ 8.77 = 0.5701254276
5 μSv = 0.5701254276 mR

About These Units
Microsievert (μSv)
A microsievert (μSv) equals 0.001 mSv or 0.1 mrem. Common exposures: dental X-ray ~5 μSv, chest X-ray 20 μSv, transatlantic flight 40-80 μSv, banana (K-40) 0.1 μSv. Most radiation meters display μSv/h for environmental monitoring.
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.
