About Converting Decigrays to Megagrays
Decigray 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: Decigray is 0.1 gray units, and megagray is 1000000 gray units.
Formula
megagrays = decigrays × 1e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 decigray equals 0.1 base units, and 1 megagray equals 1000000 base units, so dividing one by the other gives the direct decigray-to-megagray factor of 1e-7.
Simple example
1 dGy × 1e-7 = 1e-7 MGy
1 decigray = 1e-7 megagrays.
Real-world example
10 dGy × 1e-7 = 0.000001 MGy
10 decigrays = 0.000001 megagrays.

Frequently asked questions
How many megagrays are in 1 decigray?
1 decigray equals 1e-7 megagrays, using the exact defined conversion factor rather than an estimate.
How do I convert decigray to megagray?
Multiply the decigray value by 1e-7. The converter above does this instantly to whatever precision you set.
How do I convert megagray back to decigray?
Use the reverse factor: 1 megagray equals 10,000,000 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 megagray?
Megagray (MGy) is a unit of radiation.
Is the decigray to megagray conversion exact?
Yes. Both decigray and megagray are defined by fixed standards rather than physical artifacts, so the factor of 1e-7 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.
