| Symbol | Meaning |
|---|---|
| Bq | Becquerel |
| Ci | Curie |
Becquerels to Curies examples
1 Bq
1 Bq × 2.702703×10⁻¹¹ = 2.702703×10⁻¹¹ Ci.
10 Bq
10 Bq × 2.702703×10⁻¹¹ = 2.702703×10⁻¹⁰ Ci.
100 Bq
100 Bq × 2.702703×10⁻¹¹ = 2.702703×10⁻⁹ Ci.
Becquerels compared with Curies
One Ci is 37,000,000,000 times as large as one Bq, so your number gets smaller when you convert becquerels to curies and bigger when you convert back. If the answer is not smaller than what you typed, you multiplied instead of dividing.
About becquerels and curies
Becquerel (Bq): The becquerel, one decay per second. Curie (Ci): The curie, exactly 3.7×10¹⁰ Bq.
How to calculate Becquerels to Curies step by step
- Enter the value in Bq (the starting unit).
- Multiply by 2.702703×10⁻¹¹, because 1 Bq = 2.702703×10⁻¹¹ Ci.
- The product is the value in Ci. To go back, divide by 2.702703×10⁻¹¹ or multiply by 37,000,000,000.
