Privacy First: Your files are processed securely. Whenever possible, processing happens in your browser and files are never stored on our servers.

Convert radioactive activity across 14 units: SI/Becquerel (Bq, kBq, MBq, GBq, TBq, PBq, dps, dpm) and Traditional/Curie (Ci, mCi, μCi, nCi, pCi, Rutherford Rd). 1 Ci = 3.7×10¹⁰ Bq (exact); 1 Rd = 10⁶ Bq (exact). Quick-reference: K-40 in body (≈4000 Bq), PET scan dose (185–370 MBq), background radon (20–200 Bq/m³), Chernobyl release (≈5.2×10¹⁸ Bq). Sci notation essential for pCi ↔ PBq range. 100% browser-based.

How to Use

  1. 1Type a radioactivity value in the input field
  2. 2Select your starting unit (Bq, MBq, Ci, μCi, etc.) from the From dropdown
  3. 3Select your target unit in the To dropdown
  4. 4All 14 conversions appear across SI/Becquerel and Traditional/Curie groups
  5. 5Hover any row to copy or use as input
  6. 6Click ⇄ to swap From/To units
  7. 7Enable Sci notation - essential for pCi to PBq range spanning 27 orders of magnitude
  8. 8Open the quick-reference table for PET scans, background radon, and K-40 in the body
