How to convert becquerel to picocurie

1 Bq = 27.027027027027 pCi. pCi = Bq × 27.027027027027 The interactive converter uses the same unit registry as this table, so the reference values and calculator stay synchronized.

About the units

Becquerel: SI unit of radioactive activity: one nuclear transition per second.

Picocurie: One trillionth of a curie.

Radioactive activity conversion

How this activity conversion works

1 Bq = 27.027027027027 pCi. Both units describe radioactive activity, so they can be converted with a direct factor.

The SI unit becquerel (Bq) represents one nuclear transition per second. The curie relationship used here is 1 Ci = 3.7 × 10¹⁰ Bq, with metric prefixes applied consistently to the supported curie and becquerel units.

Activity is not dose. Bq cannot be converted directly to sieverts (Sv) without radionuclide, radiation, geometry, exposure pathway and other dose-model information. See Bq to Sv explained.

Capitalization matters: MBq means megabecquerel (10⁶ Bq), while mBq means millibecquerel (10⁻³ Bq). The command parser keeps those symbols distinct.

Reference definitions: BIPM curie definition and NIST SI conversion factors.

Bq to pCi FAQ

How do I convert Bq to pCi?

1 Bq = 27.027027027027 pCi. pCi = Bq × 27.027027027027

What does Bq measure?

The becquerel measures radioactive activity. One Bq corresponds to one nuclear transition per second.

Can Bq be converted directly to Sv?

No. Bq measures activity, while Sv measures dose equivalent or effective dose. Converting between them requires additional physical and exposure information, not a universal unit factor.
