Convert microsieverts to centigrays by entering a value below.
How to Convert Microsieverts to Centigrays
The microsievert and centigray are both units of radiation dose. By definition, 1 centigray equals exactly 10000 microsieverts. This means to convert microsieverts to centigrays, you divide by 10000.
Formula
Step-by-Step Example
Convert 5 μSv to centigrays:
We need to convert microsieverts to centigrays
Since 1 cGy = 10000 μSv, divide by 10000
5 ÷ 10000 = 0.0005
5 μSv = 0.0005 cGy

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.
Centigray (cGy)
A centigray (cGy) equals 0.01 gray and exactly equals 1 rad. Standard unit in radiation oncology. Typical fraction: 180-200 cGy/day. Total treatment: 4,000-8,000 cGy. Prostate: 7,000-8,000 cGy. Breast: 5,000-6,000 cGy.
