How to convert picocurie to becquerel

1 pCi = 0.037 Bq. Bq = pCi × 0.037 The interactive converter uses the same unit registry as this table, so the reference values and calculator stay synchronized.

About the units

Picocurie: One trillionth of a curie.

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

Radioactive activity conversion

How this activity conversion works

1 pCi = 0.037 Bq. 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.

pCi to Bq FAQ

How do I convert pCi to Bq?

1 pCi = 0.037 Bq. Bq = pCi × 0.037

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.
