Convert Kilobecquerels to Millicuries (kBq to mCi)
1 kilobecquerel (kBq) = 0.00002702702703 millicuries (mCi). 1 mCi = 37000 kBq. Example: 15 kBq = 15 × 0.00002702702703 = 0.0004054054054 mCi.

How to Convert Kilobecquerel to Millicurie
- 1 kBq = 0.00002702702703 mCi
- 1 mCi = 37000 kBq
- Example: convert 15 kBq to mCi: 15 kBq = 15 × 0.00002702702703 mCi = 0.0004054054054 mCi
Formula
mCi = kBq ÷ 37000
Derivation from SI units:
- 1 kBq = 10³ Bq.
- 1 mCi = 3.7 × 10⁷ Bq = 37 MBq.
- 1 kBq = 1000 Bq ÷ 37000000 Bq per mCi = 0.00002702702702703 mCi
Both units are defined exactly, so the factor is exact. Kilobecquerel definition: kilobecquerel; Millicurie definition: millicurie.
Worked examples
- A reading of 2 kBq converts to 0.00005405405405 mCi.
2 kBq × 0.00002702702703 = 0.00005405405405 mCi - A value of 20 kBq is 0.0005405405405 mCi.
20 kBq × 0.00002702702703 = 0.0005405405405 mCi

Where it's used
Kilobecquerels are used for laboratory sources and calibration standards, 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.

Frequently asked questions
How many millicuries are in 1 kilobecquerel?
1 kBq = 0.00002702702703 mCi.
How do I convert kilobecquerels to millicuries?
Multiply the value in kBq by 0.00002702702703, or divide it by 37000. For example, 15 kBq × 0.00002702702703 = 0.0004054054054 mCi.
Is the kBq 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).
