What Is This Tool?
This converter allows you to translate absorbed radiation dose values between teragray, a unit representing extremely large doses, and picogray, which measures very small doses. It facilitates conversions across a broad range of radiation dose magnitudes for scientific and technical purposes.
How to Use This Tool?
-
Enter the absorbed dose value in teragray (TGy)
-
Select the teragray as the input unit and picogray as the output unit
-
Click the convert button to see the equivalent dose in picogray (pGy)
-
Use the result for scientific comparison, calibration, or analysis purposes
Key Features
-
Converts between teragray (TGy) and picogray (pGy) units of absorbed dose
-
Browser-based and straightforward to use
-
Supports conversions relevant to nuclear safety, astrophysics, and radiation detector calibration
-
Handles extremely large and extremely small absorbed dose measurements
Examples
-
2 TGy equals 2 × 10^24 pGy or 2,000,000,000,000,000,000,000,000 pGy
-
0.5 TGy converts to 0.5 × 10^24 pGy or 5.0 × 10^23 pGy

Key Terminology
-
Teragray (TGy)
-
An SI-derived unit of absorbed dose equal to 10^12 gray, used for measuring very large energy depositions in radiation environments.
-
Picogray (pGy)
-
An SI-derived unit of absorbed dose equal to 10^-12 gray, used to quantify very small absorbed radiation doses.
-
Gray (Gy)
-
A unit of absorbed radiation dose representing one joule of energy absorbed per kilogram of matter.
