Radiology Converters
Radioactivity Converter
Convert radioactive activity between becquerels and curies. One curie is exactly 3.7×10¹⁰ decays per second (becquerels).

Frequently asked questions
What units does this radioactivity converter support?
It supports 12 units: Becquerel (Bq), Kilobecquerel (kBq), Megabecquerel (MBq), Gigabecquerel (GBq), Terabecquerel (TBq), Curie (Ci), Millicurie (mCi), Microcurie (µCi), Nanocurie (nCi), Rutherford (Rd), Disintegrations/minute (dpm), Disintegrations/second (dps).
What is the base unit of radioactivity?
The SI reference unit is the becquerel (Bq). Every conversion is computed by converting the input to the base unit, then from the base unit to the target unit, so chained precision is preserved.
Is this converter accurate?
Yes. Conversion factors use exact legal definitions where they exist (for example 1 in = 25.4 mm exactly) and CODATA/ISO constants otherwise. Results are shown to up to 10 significant figures.
