About Converting Decagrays to Megagrays
Decagray and Megagray 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: Decagray is 10 gray units, and megagray is 1000000 gray units.
Formula
megagrays = decagrays × 0.00001
This factor comes from each unit's defined relationship to the category's base unit: 1 decagray equals 10 base units, and 1 megagray equals 1000000 base units, so dividing one by the other gives the direct decagray-to-megagray factor of 0.00001.
Simple example
1 daGy × 0.00001 = 0.00001 MGy
1 decagray = 0.00001 megagrays.
Real-world example
10 daGy × 0.00001 = 0.0001 MGy
10 decagrays = 0.0001 megagrays.

Reverse conversion: Megagray to Decagray
0.00001 MGy × 100000 = 1 daGy
0.00001 megagrays = 1 decagray.
decagrays = megagrays × 100000

Frequently asked questions
How many megagrays are in 1 decagray?
1 decagray equals 0.00001 megagrays, using the exact defined conversion factor rather than an estimate.
How do I convert decagray to megagray?
Multiply the decagray value by 0.00001. The converter above does this instantly to whatever precision you set.
How do I convert megagray back to decagray?
Use the reverse factor: 1 megagray equals 100,000 decagrays. You can also use the swap control in the converter above to flip the direction instantly.
What is a decagray?
Decagray (daGy) is a unit of radiation.
What is a megagray?
Megagray (MGy) is a unit of radiation.
Is the decagray to megagray conversion exact?
Yes. Both decagray and megagray are defined by fixed standards rather than physical artifacts, so the factor of 0.00001 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.
