How this radiation-absorbed dose converter works

Gray (Gy) is used as the internal base unit. Every value you enter is first converted to Gray 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-absorbed dose relationships

  • 1 Milligray = 0.001 Gray
  • 1 Rad = 0.01 Gray

Where radiation-absorbed dose units are used

Medical physicists, radiation safety officers, and dosimetrists use these radiation units to track exposure, dose, and regulatory compliance. The radiation-absorbed dose converter covers real-world units such as Gray and Milligray, giving teams a trusted reference when cross-checking data between labs, suppliers, and regulatory filings.

Tips for accurate radiation-absorbed dose conversions

  • Always verify the unit symbol in your worksheet—this converter normalizes values through Gray, which is the SI reference for radiation-absorbed dose measurements.
  • When jumping between Gray and Milligray, 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-absorbed dose conversions so coworkers and auditors can reproduce your results.
