Becquerel to Curie Converter
Convert becquerels to curies instantly. Free, bidirectional, and fully in-browser.
1 becquerel equals 2.702703e-11 curies — enter any becquerel value to convert it to curies instantly. This Becquerel to Curie converter is a client-side tool: it applies a single multiplication (Ci = Bq × 2.702703e-11) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert curies back to becquerels. A reference table lists common becquerel values already converted, and nothing you enter is sent to a server.

Why use Becquerel to Curie Converter
Instant, both ways
The result updates as you type, and the swap button flips the conversion to curie → becquerel without reloading.
Exact Radioactivity math
The conversion uses the precise factor (Ci = Bq × 2.702703e-11), so the number matches a manual calculation to the decimal places you choose.
Adjustable precision
A slider sets 0–10 decimal places, and very small or very large results switch to scientific notation instead of rounding to zero.
Private and free
Everything runs locally in your browser — no upload, no account, no limit on conversions.
Common use cases
- Converting a becquerel measurement to curies for a spec, listing, or report.
- Checking becquerel↔curie figures while comparing products, datasets, or documentation.
- Learning the becquerel-to-curie relationship from the worked formula and the common-value table.
Frequently asked questions
How many curies are in a becquerel?
One becquerel is 2.702703e-11 curies. Multiply the becquerel value by 2.702703e-11 to convert. For example, 10 Bq = 2.702703e-10 Ci.
What is the formula to convert becquerels to curies?
Ci = Bq × 2.702703e-11. This tool applies it automatically and shows a worked example: 10 Bq = 2.702703e-10 Ci.
Can it convert curies back to becquerels?
Yes. Press the swap button, or type into the curie field, and the tool converts curies to becquerels using the inverse of the same relationship.
Is the conversion accurate?
It uses the standard radioactivity definition (Ci = Bq × 2.702703e-11), not a rounded approximation, so results are exact to the number of decimal places you select.
Does this work offline and stay private?
Yes. The converter is a browser-side script with no network calls: your values are never uploaded, and once the page has loaded it keeps working without a connection.
