Radiation Converter
Convert radiation-related units within the same physical quantity. Sievert-based and gray-based groups remain separate; the tool does not evaluate exposure risk or health effects.

How to use this tool
Choose the dose-equivalent/effective-dose group or the absorbed-dose group, then enter a value and unit. Preserve the source context, including whether it describes an accumulated dose or a rate per hour.
Results and examples
One mSv equals 1000 µSv, while one Gy equals 100 rad. Moving between Gy and Sv requires radiation and tissue weighting information rather than simply relabelling the same number.
Limitations
- Exposure-duration calculations between dose rate and accumulated dose are not included.
- Unit conversion is not a medical safety decision, a limit check or an individual risk assessment.

Frequently asked questions
How many µSv are one mSv?
One mSv equals 1000 µSv, while one Gy equals 100 rad. Moving between Gy and Sv requires radiation and tissue weighting information rather than simply relabelling the same number.
Can I directly relabel Gy as Sv?
Exposure-duration calculations between dose rate and accumulated dose are not included. Unit conversion is not a medical safety decision, a limit check or an individual risk assessment.
