Convert Microsievert to Milligray
Type the number of microsieverts that you wish to convert to milligrays.
How to Convert Microsieverts to Milligrays
The microsievert and milligray are both units of radiation dose. By definition, 1 milligray equals exactly 1000 microsieverts. This means to convert microsieverts to milligrays, you divide by 1000.
Formula
Step-by-Step Example
Convert 5 μSv to milligrays:
We need to convert microsieverts to milligrays
Since 1 mGy = 1000 μSv, divide by 1000
5 ÷ 1000 = 0.005
5 μSv = 0.005 mGy

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.
Milligray (mGy)
A milligray (mGy) equals 0.001 gray or 0.1 rad. Common medical imaging doses: CT scan 10-30 mGy, mammogram 2-3 mGy, fluoroscopy 20-50 mGy. Diagnostic reference levels often specified in mGy.
