About Converting Milligrays to Decagrays
Milligray 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: Milligray is 0.001 gray units, and decagray is 10 gray units.
Formula
decagrays = milligrays × 0.0001
This factor comes from each unit's defined relationship to the category's base unit: 1 milligray equals 0.001 base units, and 1 decagray equals 10 base units, so dividing one by the other gives the direct milligray-to-decagray factor of 0.0001.
Simple example
1 mGy × 0.0001 = 0.0001 daGy
1 milligray = 0.0001 decagrays.
Real-world example
10 mGy × 0.0001 = 0.001 daGy
10 milligrays = 0.001 decagrays.

Reverse conversion: Decagray to Milligray
0.0001 daGy × 10000 = 1 mGy
0.0001 decagrays = 1 milligray.
milligrays = decagrays × 10000

Frequently asked questions
How many decagrays are in 1 milligray?
1 milligray equals 0.0001 decagrays, using the exact defined conversion factor rather than an estimate.
How do I convert milligray to decagray?
Multiply the milligray value by 0.0001. The converter above does this instantly to whatever precision you set.
How do I convert decagray back to milligray?
Use the reverse factor: 1 decagray equals 10,000 milligrays. You can also use the swap control in the converter above to flip the direction instantly.
What is a milligray?
Milligray (mGy) is a unit of radiation.
What is a decagray?
Decagray (daGy) is a unit of radiation.
Is the milligray to decagray conversion exact?
Yes. Both milligray and decagray are defined by fixed standards rather than physical artifacts, so the factor of 0.0001 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.
