Convert curie (Ci) to becquerel (Bq) with a transparent formula and reference values.
| Curie | Becquerel |
|---|---|
| 1 Ci | 37,000,000,000 Bq |
| 5 Ci | 185,000,000,000 Bq |
| 10 Ci | 370,000,000,000 Bq |
| 25 Ci | 925,000,000,000 Bq |
| 50 Ci | 1.85e+12 Bq |
| 100 Ci | 3.7e+12 Bq |
| 500 Ci | 1.85e+13 Bq |
1 Ci = 37000000000 Bq. Bq = Ci × 37000000000 The interactive converter uses the same unit registry as this table, so the reference values and calculator stay synchronized.
Curie: Non-SI unit of radioactive activity retained for radiological use.
Becquerel: SI unit of radioactive activity: one nuclear transition per second.
1 Ci = 37000000000 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.
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 Ci = 37000000000 Bq. Bq = Ci × 37000000000
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.
