How this radiation-exposure converter works
Coulomb per Kilogram (C/kg) is used as the internal base unit. Every value you enter is first converted to Coulomb per Kilogram using exact SI factors, then translated to the requested unit with the same data pulled from the SI Brochure and NIST SP 811.
Key radiation-exposure relationships
- 1 Roentgen = 2.5800e-4 Coulomb per Kilogram
- 1 Millicoulomb per Kilogram = 0.001 Coulomb per Kilogram
Where radiation-exposure units are used
Medical physicists, radiation safety officers, and dosimetrists use these radiation units to track exposure, dose, and regulatory compliance. The radiation-exposure converter covers real-world units such as Coulomb per Kilogram and Roentgen, giving teams a trusted reference when cross-checking data between labs, suppliers, and regulatory filings.
Tips for accurate radiation-exposure conversions
- Always verify the unit symbol in your worksheet—this converter normalizes values through Coulomb per Kilogram, which is the SI reference for radiation-exposure measurements.
- When jumping between Coulomb per Kilogram and Roentgen, watch metric prefixes and rounding. A misplaced milli-, micro-, or kilo- prefix can produce errors of several orders of magnitude.
- Document the context (test conditions, instrument resolution, uncertainty) whenever you publish radiation-exposure conversions so coworkers and auditors can reproduce your results.
