How to Convert Terabecquerel to Millicurie
- 1 TBq = 27027.02703 mCi
- 1 mCi = 0.000037 TBq
- Example: convert 15 TBq to mCi: 15 TBq = 15 × 27027.02703 mCi = 405405.4054 mCi
Formula
mCi = TBq × 27027.02702703
Derivation from SI units:
- 1 TBq = 10¹² Bq.
- 1 mCi = 3.7 × 10⁷ Bq = 37 MBq.
- 1 TBq = 1000000000000 Bq ÷ 37000000 Bq per mCi = 27027.02702703 mCi
Both units are defined exactly, so the factor is exact. Terabecquerel definition: terabecquerel; Millicurie definition: millicurie.
Worked examples
- A reading of 2 TBq converts to 54054.05405 mCi.
2 TBq × 27027.02703 = 54054.05405 mCi - A value of 20 TBq is 540540.5405 mCi.
20 TBq × 27027.02703 = 540540.5405 mCi

Where it's used
Terabecquerels are used for cobalt-60 and iridium-192 sources, while millicuries appear in US radiopharmaceutical doses (e.g. 10 mCi FDG). Both measure activity of a radioactive source, so the conversion is a fixed factor.
