Understanding your result
The converted value describes the same radiation exposure 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.
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 convert Roentgens to Microcoulombs per kilogram?
Enter the known measurement and select its source and target units. The converter expresses the same photon radiation exposure 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. Exposure for X/gamma radiation; not absorbed dose. Do not convert roentgens to grays as a unit conversion. 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 R equals approximately 2580 µC/kg. Reverse the units to convert in the other direction.
