What does 1 kilogray represent?

One kilogray equals 1,000 grays, where one gray is the absorption of one joule energy per kilogram of matter.

When should I use exagray as a unit?

Exagray is used to express extraordinarily large radiation absorbed doses, often in astrophysical or theoretical high-energy physics contexts.

Why isn’t exagray used for everyday dose measurements?

Because the exagray unit represents an enormous magnitude (10^18 grays), it is impractical for typical dose levels encountered in industry or medicine.

What Is This Tool?

This unit converter tool enables users to transform absorbed radiation dose values from kilogray (kGy) to exagray (EGy). It assists in comparing practical dose measurements with theoretical or extreme scientific radiation doses expressed on a vastly larger scale.

How to Use This Tool?

Enter the absorbed dose value in kilogray (kGy).
Select kilogray as the input unit and exagray as the output unit.
Click the convert button to see the equivalent value in exagray (EGy).
Review the result to understand dose comparisons between practical and theoretical scales.

Key Features

Converts radiation absorbed dose values from kilogray to exagray.
Provides exact conversion using the defined rate: 1 kGy = 1e-15 EGy.
Includes examples illustrating practical and theoretical uses.
Browser-based and easy to use with no installation required.

Examples

1000 kGy converts to 1e-12 EGy using the formula 1000 × 1e-15 EGy.
A typical sterilization dose of 25 kGy equals 2.5e-14 EGy.
Use the tool to express industrial doses as much smaller exagray values in theoretical contexts.

Common Use Cases

Sterilization of medical devices and pharmaceutical products at around 25 kGy.
Food irradiation treatments up to approximately 10 kGy for preservation.
Polymer modification and materials testing using gamma or electron-beam irradiation spanning a few to hundreds of kGy.
Astrophysics modelling of extreme radiation events such as gamma-ray bursts with very large dose scales in exagray.
High-energy physics and nuclear explosion energy deposition calculations requiring compact representation of vast doses.

Tips & Best Practices

Use kilogray for practical dose measurements in industrial and medical applications.
Convert to exagray only when dealing with exceptionally large or theoretical radiation doses.
Refer to conversion examples to validate calculations between units.
Understand the context and scale before interpreting exagray results, as this unit is uncommon in daily use.

Limitations

Exagray is not suitable for everyday absorbed dose measurements due to its extremely large magnitude.
Typical dose values are reported in grays, kilograys, or megarays rather than exagray.
Conversion to exagray is mostly relevant in theoretical or very high energy scientific studies.
The tool does not provide rounding or precision adjustments—values reflect direct conversions only.
