Quick Answer
Convert between the units used across nuclear medicine — activity (Ci ↔ Bq: mCi ↔ MBq, µCi ↔ kBq), absorbed dose (Gy ↔ rad), and equivalent/effective dose (Sv ↔ rem) — using exact definitional factors. Enter a value and its unit and every equivalent is shown at once.

Exact definitional factors. Activity: 1 Ci = 3.7×10¹⁰ Bq = 37 GBq, so 1 mCi = 37 MBq. Absorbed dose: 1 Gy = 100 rad (1 cGy = 1 rad). Equivalent/effective dose: 1 Sv = 100 rem.
