What does the rad unit measure?

The rad is a legacy unit for absorbed radiation dose, quantifying energy deposited by ionizing radiation per unit mass with 1 rad equal to 0.01 gray.

When should I use exagray units?

Exagray is used to express extremely large absorbed doses, mostly in scientific fields like astrophysics or nuclear physics dealing with theoretical or enormous energy depositions.

Why convert rad to exagray?

Converting from rad to exagray helps relate historical or legacy radiation dose information to very large-scale doses expressed in standard SI multiples for scientific comparison.

What Is This Tool?

This converter enables you to change radiation absorbed dose values from the rad, a traditional unit, into the exagray, an exceptionally large SI multiple of the gray. It is designed for contexts requiring the expression of extremely high radiation doses in scientific or theoretical research.

How to Use This Tool?

Enter the value in rad (rd) you wish to convert.
Select rad as the source unit and exagray (EGy) as the target unit.
Click the convert button to see the equivalent dose in exagray.
Review the result, which reflects the extremely large scaling of exagray units.

Key Features

Supports conversion between rad (rd) and exagray (EGy) units.
Based on the official conversion factor: 1 Rad equals 1 × 10⁻²⁰ Exagray.
Ideal for representing absorbed dose in astrophysics and high-energy physics.
Enables interpretation of legacy radiation records with modern SI units.
Browser-based and user-friendly interface for quick conversions.

Examples

100 Rad converts to 1e-18 Exagray (EGy).
5,000 Rad converts to 5e-17 Exagray (EGy).

Common Use Cases

Interpreting historical radiotherapy data in modern scientific contexts.
Modeling extreme radiation exposure in astrophysics, such as gamma-ray bursts.
Calculating large energy depositions in nuclear explosion research.
Expressing extraordinary radiation fluences in high-energy physics simulations.

Tips & Best Practices

Use this converter when dealing with very large scales of radiation dose.
Remember that rad is a legacy unit often replaced by gray in current practice.
Verify context to ensure exagray is appropriate for representing dose magnitude.
Understand that converted values will be very small due to the unit sizes.

Limitations

Exagray measurements are theoretical and represent extraordinarily large doses rarely seen practically.
Conversion results often yield very small numbers limiting everyday applicability.
Rad remains a legacy unit and is not commonly used in contemporary measurements.
The converter focuses on this specific unit pair and does not cover other radiation units.
