Enter the number of microsieverts that you want to convert to milliroentgens.

1 μSv (microsieverts) = 0.1140250855 mR (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

milliroentgens = microsieverts ÷ 8.77

Step-by-Step Example

Convert 5 μSv to milliroentgens:

1
Convert 5 μSv to milliroentgens

We need to convert microsieverts to milliroentgens

2
Apply the formula

Since 1 mR = 8.77 μSv, divide by 8.77

5 ÷ 8.77 = 0.5701254276

Answer

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.
