What is the conversion factor from gray to microgray?

One gray equals one million microgray, so multiply gray values by 1,000,000 to convert.

Why would I convert gray to microgray?

Microgray units are useful for measuring and reporting very low-level radiation doses in environmental monitoring, diagnostic imaging, and radiation protection.

Does this conversion account for biological effects?

No, the conversion is purely physical and does not consider biological effect weighting, which requires conversion to sieverts.

What Is This Tool?

This tool converts radiation absorbed dose values from gray (Gy), the SI unit of absorbed dose, to microgray (µGy), an SI derived unit representing much smaller doses. It assists users needing to express radiation exposure at varied scales in medical, environmental, and industrial contexts.

How to Use This Tool?

Enter the absorbed dose value in gray (Gy).
Confirm that the source unit is set to gray (Gy) and the target unit is microgray (µGy).
Click the convert button to obtain the equivalent dose in microgray.
Refer to provided examples to verify your results.
Use the converted value for low-level radiation dose reporting or further analysis.

Key Features

Converts absorbed dose from gray (Gy) to microgray (µGy) using the exact conversion factor.
Supports applications in radiotherapy, radiation protection, environmental monitoring, and aerospace radiation assessment.
Provides clear unit definitions and examples for better understanding.
Browser-based interface requiring no installation.
Suitable for both clinical and scientific dose measurement tasks.

Examples

0.5 Gy converts to 500,000 µGy by multiplying with 1,000,000.
0.002 Gy equals 2,000 µGy using the same conversion factor.

Common Use Cases

Prescribing and recording doses in external beam radiotherapy and brachytherapy.
Calibrating radiation detectors and dosimeters in clinical and industrial settings.
Carrying out environmental monitoring of low-level radiation exposure.
Reporting doses from low-dose diagnostic imaging procedures.
Assessing radiation exposure for aviation and spacecraft crews.

Tips & Best Practices

Double-check unit selections before converting to avoid errors.
Use precise measurement instruments when working with microgray doses.
Consider that biological effect weighting requires further unit conversions.
Leverage examples to familiarize yourself with typical conversion results.
Apply this tool for both clinical and research dose quantification needs.

Limitations

Microgray values require sensitive, well-calibrated instruments to ensure accuracy.
Conversion does not incorporate biological effect weighting; sievert conversion is needed for health risk assessments.
This tool only handles conversion between gray and microgray units and does not perform other unit conversions.
