About Converting Decigrays to Centigrays
Decigray and Centigray both belong to the radiation-measurement family, though radiation quantities fall into genuinely distinct categories: absorbed dose (gray, rad) measures energy deposited in matter, equivalent dose (sievert, rem) weights that for biological harm, and activity (becquerel, curie) measures how often a radioactive source decays — this page only converts between units of the same kind. Specifically: Decigray is 0.1 gray units, and centigray is 0.01 gray units.
Formula
centigrays = decigrays × 10
This factor comes from each unit's defined relationship to the category's base unit: 1 decigray equals 0.1 base units, and 1 centigray equals 0.01 base units, so dividing one by the other gives the direct decigray-to-centigray factor of 10.
Simple example
1 dGy × 10 = 10 cGy
1 decigray = 10 centigrays.
Real-world example
10 dGy × 10 = 100 cGy
10 decigrays = 100 centigrays.

Frequently asked questions
How many centigrays are in 1 decigray?
1 decigray equals 10 centigrays, using the exact defined conversion factor rather than an estimate.
How do I convert decigray to centigray?
Multiply the decigray value by 10. The converter above does this instantly to whatever precision you set.
How do I convert centigray back to decigray?
Use the reverse factor: 1 centigray equals 0.1 decigrays. You can also use the swap control in the converter above to flip the direction instantly.
What is a decigray?
Decigray (dGy) is a unit of radiation.
What is a centigray?
Centigray (cGy) is a unit of radiation.
Is the decigray to centigray conversion exact?
Yes. Both decigray and centigray are defined by fixed standards rather than physical artifacts, so the factor of 10 used above is exact to as many digits as you choose to display.
What's the difference between absorbed dose, equivalent dose, and activity?
Absorbed dose (gray, rad) measures the energy radiation deposits in matter. Equivalent dose (sievert, rem) adjusts that figure for how harmful different types of radiation are to biological tissue. Activity (becquerel, curie) measures how often a radioactive source decays, independent of how much dose a person actually receives from it.
