Formula
Step-by-Step Example
Convert 5 μGy to centigrays:
We need to convert micrograys to centigrays
Since 1 cGy = 10000 μGy, divide by 10000
5 ÷ 10000 = 0.0005
5 μGy = 0.0005 cGy

About These Units
Microgray (μGy)
A microgray (μGy) equals 0.001 mGy or 0.1 mrad. Chest X-ray: ~20 μGy. Panoramic dental X-ray: 10-20 μGy. Used for specifying doses from diagnostic imaging with minimal exposure. One gray = one million micrograys.
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.
