About Converting Decigrays to Milligrays
Decigray and Milligray 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 milligray is 0.001 gray units.
Formula
milligrays = decigrays × 100
This factor comes from each unit's defined relationship to the category's base unit: 1 decigray equals 0.1 base units, and 1 milligray equals 0.001 base units, so dividing one by the other gives the direct decigray-to-milligray factor of 100.
Simple example
1 dGy × 100 = 100 mGy
1 decigray = 100 milligrays.
Real-world example
10 dGy × 100 = 1,000 mGy
10 decigrays = 1,000 milligrays.

Reverse conversion: Milligray to Decigray
100 mGy × 0.01 = 1 dGy
100 milligrays = 1 decigray.
decigrays = milligrays × 0.01

Frequently asked questions
How many milligrays are in 1 decigray?
1 decigray equals 100 milligrays, using the exact defined conversion factor rather than an estimate.
How do I convert decigray to milligray?
Multiply the decigray value by 100. The converter above does this instantly to whatever precision you set.
How do I convert milligray back to decigray?
Use the reverse factor: 1 milligray equals 0.01 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 milligray?
Milligray (mGy) is a unit of radiation.
Is the decigray to milligray conversion exact?
Yes. Both decigray and milligray are defined by fixed standards rather than physical artifacts, so the factor of 100 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.
