What is the relationship between hectogray and gray?

One hectogray equals 100 grays, which means 1 hGy = 100 Gy.

In which fields is converting from hectogray to gray commonly used?

This conversion is often applied in industrial radiation processing, radiation hardness testing, medical radiotherapy, and dosimetry laboratory work.

Does this conversion consider biological radiation effects?

No, the conversion is purely based on physical absorbed dose values and does not include biological effect weighting.

What Is This Tool?

This converter allows you to transform absorbed radiation dose measurements from hectogray (hGy), an SI-derived unit representing 100 grays, into gray (Gy), the base SI unit of absorbed radiation energy per kilogram. It is ideal for applications involving calibration, therapy dosage, and radiation protection assessment.

How to Use This Tool?

Enter the radiation absorbed dose value in hectogray (hGy).
Select hectogray as the source unit and gray as the target unit.
Click the convert button to see the equivalent dose in grays.
Use the result for your dosimetry, radiation therapy, or calibration tasks.

Key Features

Straightforward conversion between hectogray and gray units.
Supports doses commonly used in industrial, medical, and research settings.
Browser-based tool requiring no installation.
Useful for high-dose radiation measurements and calibration.

Examples

2 hGy converts to 200 Gy.
0.5 hGy converts to 50 Gy.

Common Use Cases

Reporting intermediate high doses in industrial radiation processing like material modification.
Radiation-hardness testing of electronics and materials at high absorbed doses.
Calibrating dosimeters and conducting dosimetry in specialized laboratories.
Prescribing and documenting therapeutic radiation doses in medical radiotherapy.

Tips & Best Practices

Use this tool for converting large absorbed dose values to the base gray unit for accuracy.
Avoid using hectogray for low or clinical dose ranges to prevent imprecision.
Remember to consider biological weighting factors separately when evaluating biological effects.
Verify converted values are consistent with your application’s dose scale requirements.

Limitations

The hectogray unit is mainly suited for very high absorbed doses.
Conversions do not account for biological effect weighting factors.
For lower doses, the gray or its subunits provide more appropriate precision.
