What to enter
| Input | Meaning and units |
|---|---|
| Value | Enter value using the definition in the method and example. |
| From | Select the unit or currency in which the entered number is currently expressed. |
| To | Select the unit or currency you need for the answer. |
Understanding your result
The converted value describes the same equivalent dose quantity in the selected target unit. Display rounding does not add precision to the original measurement.
Common mistakes
- Confusing the source and target units, or overlooking a prefix or case-sensitive symbol.
- Treating an equivalent-dose value as an absorbed dose or a clinical safety assessment.
Check your calculation
- Convert to the target unit and then reverse the direction. Within display rounding, you should recover the original value.

How do I express equivalent radiation dose in another unit?
Enter the known measurement and select its source and target units. The converter expresses the same equivalent radiation dose quantity in the target unit, using the stated definitions.
Common uses
- Compare measurements stated in different units.
- Translate a known value before using it in a formula or specification.
How it works
Convert through the shared base quantity using the two defined factors. Unit conversion only. Effective dose and equivalent dose use different weighting definitions; labels must preserve original quantity. Conversion changes the unit of a known measurement; it does not calculate another physical quantity or imply a material model. Factors with π or repeating rational values use finite precision; results display up to 12 significant digits.
Worked example
10 Sv equals approximately 10000 mSv. Reverse the units to convert in the other direction.
