What does microgray (µGy) measure?

Microgray (µGy) is an SI derived unit measuring absorbed radiation dose equal to one millionth of a gray, used mainly in environmental and diagnostic radiation monitoring.

When is gigagray (GGy) used?

Gigagray (GGy) measures extraordinarily large absorbed doses, typically in advanced scientific research such as nuclear materials testing and astrophysical modeling.

How do I convert microgray to gigagray?

You multiply the microgray value by 1e-15 to get the equivalent dose in gigagray units.

Use the converted figure for research, reporting, or theoretical modeling purposes.

Key Features

Converts absorbed dose values between microgray and gigagray units.
Based on the SI-derived units for radiation absorbed dose.
Offers quick conversion using the precise conversion rate of 1 µGy = 1e-15 GGy.
Ideal for use in radiation protection, medical diagnostics, astrophysics, and nuclear testing contexts.

Examples

500 microgray (µGy) equals 5e-13 gigagray (GGy).
1000 microgray (µGy) equals 1e-12 gigagray (GGy).

Common Use Cases

Monitoring low-level radiation in the environment and workplaces.
Reporting doses from low-dose diagnostic imaging such as dental or chest x-rays.
Studying extreme radiation exposures in materials testing and nuclear-effects analysis.
Researching astrophysical phenomena involving very large radiation doses.
Evaluating worst-case radiation damage in high-energy accelerator environments.

Tips & Best Practices

Double-check unit selections before converting to avoid errors.
Use this tool to relate typical low-dose measurements to extreme dose scenarios.
Apply conversions carefully in scientific modeling or safety analyses due to scale differences.
Understand that microgray suits routine monitoring, while gigagray applies only to extraordinary doses.

Limitations

Microgray units represent low-level absorbed doses, whereas gigagray units apply to exceptionally high dose ranges.
Direct practical equivalence between these units is rare because of the immense scale difference involved.
This conversion is mainly relevant in highly specialized scientific and technical contexts.
