How to Convert Megabecquerel to Millicurie
- 1 MBq = 0.02702702703 mCi
- 1 mCi = 37 MBq
- Example: convert 370 MBq to mCi: 370 MBq = 370 × 0.02702702703 mCi = 10 mCi
Formula
mCi = MBq ÷ 37
Derivation from SI units:
- 1 MBq = 10⁶ Bq.
- 1 mCi = 3.7 × 10⁷ Bq = 37 MBq.
- 1 MBq = 1000000 Bq ÷ 37000000 Bq per mCi = 0.02702702702703 mCi
Both units are defined exactly, so the factor is exact. Megabecquerel definition: megabecquerel; Millicurie definition: millicurie.
Worked examples
- A 370 MBq dose is 10 mCi.
370 MBq × 0.02702702703 = 10 mCi - A 740 MBq bone scan dose is 20 mCi.
740 MBq × 0.02702702703 = 20 mCi

Frequently asked questions
How do I convert MBq to mCi?
Divide by 37: 370 MBq = 10 mCi.
How many millicuries are in 1 megabecquerel?
1 MBq = 0.02702702703 mCi.
How do I convert megabecquerels to millicuries?
Multiply the value in MBq by 0.02702702703, or divide it by 37. For example, 370 MBq × 0.02702702703 = 10 mCi.
Is the MBq to mCi conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
