Convert becquerel (Bq) to curie (Ci) with a transparent formula and reference values.
| Becquerel | Curie |
|---|---|
| 1 Bq | 2.7027027e-11 Ci |
| 5 Bq | 1.35135135e-10 Ci |
| 10 Bq | 2.7027027e-10 Ci |
| 25 Bq | 6.75675676e-10 Ci |
| 50 Bq | 1.35135135e-9 Ci |
| 100 Bq | 2.7027027e-9 Ci |
| 500 Bq | 1.35135135e-8 Ci |
1 Bq = 2.7027027027027e-11 Ci. Ci = Bq × 2.7027027027027e-11 The interactive converter uses the same unit registry as this table, so the reference values and calculator stay synchronized.
Becquerel: SI unit of radioactive activity: one nuclear transition per second.
Curie: Non-SI unit of radioactive activity retained for radiological use.
1 Bq = 2.7027027027027e-11 Ci. 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.
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.
1 Bq = 2.7027027027027e-11 Ci. Ci = Bq × 2.7027027027027e-11
The becquerel measures radioactive activity. One Bq corresponds to one nuclear transition per second.
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.
