Complete List of Radiation Units for Conversion
1 Millisievert [mSv] = 0.00100000 Sievert [Sv]
1 Microsievert [µSv] = 0.00000100000 Sievert [Sv]
1 Rem [rem] = 0.0100000 Sievert [Sv]
1 Millirem [mrem] = 0.0000100000 Sievert [Sv]
How this radiation converter works
Sievert (Sv) is used as the internal base unit. Every value you enter is first converted to Sievert 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 relationships
- 1 Millisievert = 0.001 Sievert
- 1 Microsievert = 1.0000e-6 Sievert
- 1 Rem = 0.01 Sievert
- 1 Millirem = 1.0000e-5 Sievert
Where radiation units are used
Medical physicists, radiation safety officers, and dosimetrists use these radiation units to track exposure, dose, and regulatory compliance. The radiation converter covers real-world units such as Sievert and Millisievert, giving teams a trusted reference when cross-checking data between labs, suppliers, and regulatory filings.
Tips for accurate radiation conversions
- Always verify the unit symbol in your worksheet—this converter normalizes values through Sievert, which is the SI reference for radiation measurements.
- When jumping between Sievert and Millisievert, 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 conversions so coworkers and auditors can reproduce your results.
