Convert Megabecquerels to Kilocuries
Convert Megabecquerels (MBq) to Kilocuries (kCi) instantly and accurately.
Conversion Formula
kCi = MBq × 2.702702703e-8
About Megabecquerels
The megabecquerel (MBq) equals 10⁶ Bq and is the standard clinical nuclear medicine unit outside the US. ⁹⁹mTc bone scans use 740 MBq; ¹⁸F-FDG PET scans use 370 MBq; ¹³¹I diagnostic thyroid scans use 185-370 MBq. European and Australian protocols specify all doses in MBq. 1 MBq = 10⁶ Bq.
About Kilocuries
The kilocurie (kCi) equals 3.7 × 10¹³ Bq. ⁶⁰Co and ¹³⁷Cs blood irradiation and food sterilisation facilities use 20-200 kCi sources; research reactor fission product inventories are characterised in kCi; ⁹⁰Sr/⁹⁰Y radioisotope thermoelectric generators (RTGs) contain 10-150 kCi. 1 kCi = 3.7 × 10¹³ Bq.
