Convert radiation dose equivalent across 9 units: SI (Sv, mSv, μSv, nSv, pSv, J/kg) and Traditional (rem, mrem, μrem). 1 Sv = 100 rem (exact). Quick-reference covers background radiation (≈2.4 mSv/year), chest X-ray (≈0.1 mSv), CT scan (≈7 mSv), flight radiation, and occupational limit (20 mSv/year). Distinct from absorbed dose (Gray) and exposure (Roentgen). 100% browser-based.
