Reference
How radiation - exposure conversion works
Radiation exposure quantifies ionization produced in air and is distinct from absorbed or equivalent dose. Values are normalized to Coulomb/kilogram before conversion to the requested output unit.
Values are converted to coulomb/kilogram first, then from that reference into the requested unit. Keeping a single documented reference reduces inconsistent pair-by-pair constants.

Questions
Radiation - Exposure FAQ
What is the reference unit for radiation - exposure conversions?
ConvertWin uses coulomb/kilogram (C/kg) as the internal reference for this category, then converts to the selected output unit.
How accurate is this radiation - exposure converter?
SI relationships follow the cited reference. Conventional and domain-specific factors use the established ConvertWin factor inventory; verify safety-critical work against the governing standard.
