Convert Millicuries to Terabecquerels (mCi to TBq)
1 millicurie (mCi) = 0.000037 terabecquerels (TBq). 1 TBq = 27027.02703 mCi. Example: 15 mCi = 15 × 0.000037 = 0.000555 TBq.

How to Convert Millicurie to Terabecquerel
- 1 mCi = 0.000037 TBq
- 1 TBq = 27027.02703 mCi
- Example: convert 15 mCi to TBq: 15 mCi = 15 × 0.000037 TBq = 0.000555 TBq
Formula
TBq = mCi × 0.000037
or TBq = mCi ÷ 27027.02702703
Derivation from SI units:
- 1 mCi = 3.7 × 10⁷ Bq = 37 MBq.
- 1 TBq = 10¹² Bq.
- 1 mCi = 37000000 Bq ÷ 1000000000000 Bq per TBq = 0.000037 TBq
Both units are defined exactly, so the factor is exact. Millicurie definition: millicurie; Terabecquerel definition: terabecquerel.
Worked examples
- A reading of 15 mCi converts to 0.000555 TBq.
15 mCi × 0.000037 = 0.000555 TBq - A value of 30 mCi is 0.00111 TBq.
30 mCi × 0.000037 = 0.00111 TBq

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