Convert Megacuries per kilogram to Millicuries per kilogram
Convert Megacuries per kilogram (MCi/kg) to Millicuries per kilogram (mCi/kg) instantly and accurately.
Conversion Formula
mCi/kg = MCi/kg × 1000000000
About Megacuries per kilogram
The megacurie per kilogram (MCi/kg) equals 3.7 × 10¹⁶ Bq/kg. Encountered for extremely high-specific-activity nuclides: carrier-free ²²³Ra (α-emitter, t½ = 11.43 d) reaches ~50 MCi/kg; polonium-210 freshly separated from bismuth targets in research reactors has a specific activity near 4.5 MCi/g = 4.5 × 10³ MCi/kg. 1 MCi/kg = 3.7 × 10¹⁶ Bq/kg.
About Millicuries per kilogram
The millicurie per kilogram (mCi/kg) equals 3.7 × 10⁷ Bq/kg = 37 MBq/kg. Radiopharmaceutical preparations are sometimes characterised in mCi/kg when assessing organ uptake per body mass; ⁹⁹mTc-labelled compounds have specific activities in the mCi/µmol range that translate to high mCi/kg values. 1 mCi/kg = 3.7 × 10⁷ Bq/kg.
