What Is This Tool?
This converter allows users to change radiation absorbed dose values from petagray to dekagray. Both units describe energy absorbed from ionizing radiation per kilogram of material, with petagray being suited for extremely large doses and dekagray used for expressing doses in tens of grays.
How to Use This Tool?
-
Enter the radiation dose value in petagray (PGy).
-
Select petagray as the original unit and dekagray as the target unit.
-
Click convert to get the equivalent value in dekagray (daGy).
-
Use the result to analyze or report radiation absorbed dose levels in the desired unit.
Key Features
-
Converts petagray values to dekagray using a fixed conversion rate.
-
Supports units relevant for astrophysics, high-energy physics, and radiation protection.
-
Simple interface for converting extremely large absorbed dose quantities.
-
Browser-based and easy to access for quick calculations.
Examples
-
1 PGy converts to 100,000,000,000,000 daGy.
-
0.5 PGy converts to 50,000,000,000,000 daGy.
Common Use Cases
-
Modeling energy deposition in supernovae or extreme astrophysical events.
-
Simulating ultra-high-dose radiation scenarios in particle physics experiments.
-
Expressing radiotherapy treatment totals in radiotherapy planning.
-
Describing high-level exposure in radiation protection or accident assessments.
-
Reporting intermediate industrial irradiation doses where smaller units are preferred.
Tips & Best Practices
-
Use petagray for theoretical or ultra-high radiation scenarios only.
-
Apply dekagray for doses measured in tens of grays when more manageable units are needed.
-
Verify the context of radiation dose to ensure appropriate unit selection.
-
Remember the conversion is primarily for analysis in astrophysics and high-energy physics research.
Limitations
-
Petagray is unsuitable for common medical or environmental radiation levels.
-
Conversions mainly serve academic or simulation purposes due to scale differences.
-
Not applicable for typical radiation dose measurements in everyday settings.
Frequently Asked Questions

Dekagray is preferred for expressing doses in tens of grays, such as in radiotherapy totals or radiation protection assessments.
Key Terminology
-
Petagray (PGy)
-
An SI-derived unit of absorbed dose equal to 10^15 grays, used for extremely large or theoretical radiation doses.
-
Dekagray (daGy)
-
A metric multiple of gray representing 10 grays, used to express moderate high-level radiation doses.
-
Gray (Gy)
-
The SI unit of absorbed radiation dose, defined as one joule of energy absorbed per kilogram of matter.
