About the units

Centigray (cGy)

The centigray (cGy) is a unit of absorbed radiation dose in the International System of Units (SI). One centigray equals 0.01 grays (Gy).

Milligray (mGy)

A chest CT delivers on the order of a few to ten mGy. One milligray equals 0.001 grays (Gy).

Frequently asked questions

How many milligrays are in one centigray?

There are 10 milligrays in one centigray, and this value is exact by definition.

How do I convert centigrays to milligrays?

Multiply the number of centigrays by 10. For example, 10 cGy × 10 = 100 mGy.

How many centigrays are in one milligray?

One milligray equals 0.1 centigrays. That is the reverse factor, 1 ÷ 10.

What is 10 centigrays in milligrays?

10 cGy = 100 mGy.

Is this cGy to mGy converter accurate?

Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
