What does 1 centigray represent?

1 centigray (cGy) equals one hundredth of a gray (0.01 Gy), which quantifies the energy absorbed by matter from ionizing radiation per kilogram.

Why use megagray units?

Megagray (MGy) expresses extremely large absorbed radiation doses, useful for studies involving severe radiation damage or high-intensity scenarios.

How do I convert centigray to megagray?

Multiply the value in centigray by 1e-8 to get the equivalent dose in megagray.

What Is This Tool?

This online converter allows users to transform absorbed radiation dose measurements from centigray (cGy) to megagray (MGy). It supports professionals working in medical physics, radiotherapy, nuclear medicine, and radiation-damage research by facilitating conversions between clinical dose levels and extremely large absorbed doses.

How to Use This Tool?

Enter the value in centigray (cGy) that you want to convert.
Select centigray as the input unit and megagray as the output unit.
Click the convert button to get the equivalent value in megagray (MGy).
Review the output which reflects the very small converted value due to the large unit scale difference.

Key Features

Converts absorbed radiation dose values from centigray to megagray.
Provides a straightforward formula for conversion: 1 cGy equals 1e-8 MGy.
Supports use in medical and scientific fields including radiation therapy and material testing.
Browser-based tool with simple input and output interface.
Great for expressing radiation doses across vastly different scales.

Examples

100 cGy converts to 1e-6 MGy by multiplying 100 × 1e-8.
200 cGy converts to 2e-6 MGy applying the conversion factor 1e-8.

Common Use Cases

Documenting radiation doses in external beam radiotherapy and nuclear medicine.
Calibrating therapeutic radiation beams and verifying dosimeter readings in medical physics.
Describing extremely high absorbed doses in radiation-damage studies of materials and structures.
Specifying cumulative or peak doses in radiation-hardness testing of electronic devices.
Estimating dose levels in catastrophic or high-intensity radiation scenarios.

Tips & Best Practices

Always confirm units before converting due to large differences in scale between cGy and MGy.
Use scientific notation to clearly represent very small converted values.
Review and verify conversions especially for critical or technical applications.
Understand the context in which the conversion applies to avoid misinterpretation.

Limitations

Conversion results in very small numbers often limiting its practical use outside high-dose quantification.
Requires careful handling of scientific notation and unit scale awareness.
Not intended for direct clinical dose comparisons without considering context and scale.
