About Converting Teragrays to Decagrays
Teragray 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: Teragray is 1000000000000 gray units, and decagray is 10 gray units.
Formula
decagrays = teragrays × 100000000000
This factor comes from each unit's defined relationship to the category's base unit: 1 teragray equals 1e+12 base units, and 1 decagray equals 10 base units, so dividing one by the other gives the direct teragray-to-decagray factor of 100000000000.
Simple example
1 TGy × 100000000000 = 100,000,000,000 daGy
1 teragray = 100,000,000,000 decagrays.
Real-world example
10 TGy × 100000000000 = 1e+12 daGy
10 teragrays = 1e+12 decagrays.

Reverse conversion: Decagray to Teragray
1 daGy × 1e-11 = 1e-11 TGy
1 decagray = 1e-11 teragrays.
teragrays = decagrays × 1e-11

Frequently asked questions
How many decagrays are in 1 teragray?
1 teragray equals 100,000,000,000 decagrays, using the exact defined conversion factor rather than an estimate.
How do I convert teragray to decagray?
Multiply the teragray value by 100000000000. The converter above does this instantly to whatever precision you set.
How do I convert decagray back to teragray?
Use the reverse factor: 1 decagray equals 1e-11 teragrays. You can also use the swap control in the converter above to flip the direction instantly.
What is a teragray?
Teragray (TGy) is a unit of radiation.
What is a decagray?
Decagray (daGy) is a unit of radiation.
Is the teragray to decagray conversion exact?
Yes. Both teragray and decagray are defined by fixed standards rather than physical artifacts, so the factor of 100000000000 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.
