About Converting Centigrays to Decagrays
Centigray and Decagray 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: Centigray is 0.01 gray units, and decagray is 10 gray units.
Formula
decagrays = centigrays × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 centigray equals 0.01 base units, and 1 decagray equals 10 base units, so dividing one by the other gives the direct centigray-to-decagray factor of 0.001.
Simple example
1 cGy × 0.001 = 0.001 daGy
1 centigray = 0.001 decagrays.
Real-world example
10 cGy × 0.001 = 0.01 daGy
10 centigrays = 0.01 decagrays.

Frequently asked questions
How many decagrays are in 1 centigray?
1 centigray equals 0.001 decagrays, using the exact defined conversion factor rather than an estimate.
How do I convert centigray to decagray?
Multiply the centigray value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert decagray back to centigray?
Use the reverse factor: 1 decagray equals 1,000 centigrays. You can also use the swap control in the converter above to flip the direction instantly.
What is a centigray?
Centigray (cGy) is a unit of radiation.
What is a decagray?
Decagray (daGy) is a unit of radiation.
Is the centigray to decagray conversion exact?
Yes. Both centigray and decagray are defined by fixed standards rather than physical artifacts, so the factor of 0.001 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.
