Convert Megacuries to Picocuries
Convert Megacuries (MCi) to Picocuries (pCi) instantly and accurately.
Conversion Formula
pCi = MCi × 1.000000000e+18
About Megacuries
The megacurie (MCi) equals 3.7 × 10¹⁶ Bq. Total radioactive inventory of a large nuclear power reactor core at shutdown is ~2000-10000 MCi; US atmospheric nuclear weapons tests released ~12000 MCi of ¹³¹I globally; high-level nuclear waste repositories are characterised in MCi. 1 MCi = 3.7 × 10¹⁶ Bq.
About Picocuries
The picocurie (pCi) equals 3.7 × 10⁻² Bq = 37 mBq. The US EPA uses pCi/L as the standard unit for indoor radon (action level: 4 pCi/L) and drinking water radon; NRC licence exemption thresholds and natural uranium activity in groundwater are expressed in pCi/L. 1 pCi = 3.7 × 10⁻² Bq.
