Convert Megabecquerels to Gigacuries
Convert Megabecquerels (MBq) to Gigacuries (GCi) instantly and accurately.
Conversion Formula
GCi = MBq × 2.702702703e-14
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 Gigacuries
The gigacurie (GCi) equals 3.7 × 10¹⁹ Bq. The total fission product inventory of a 1 GWe nuclear power reactor at equilibrium is ~0.5 GCi; global spent fuel inventories worldwide exceed 10 GCi; total reactor-produced tritium in the world's oceans is estimated at ~1 GCi. 1 GCi = 3.7 × 10¹⁹ Bq.
