Curie to Becquerel Converter
Convert curies to becquerels instantly. Free, bidirectional, and fully in-browser.
1 curie equals 37000000000 becquerels — enter any curie value to convert it to becquerels instantly. This Curie to Becquerel converter is a client-side tool: it applies a single multiplication (Bq = Ci × 37000000000) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert becquerels back to curies. A reference table lists common curie values already converted, and nothing you enter is sent to a server.
How to use Curie to Becquerel Converter

Why use Curie to Becquerel Converter
Instant, both ways
The result updates as you type, and the swap button flips the conversion to becquerel → curie without reloading.
Exact Radioactivity math
The conversion uses the precise factor (Bq = Ci × 37000000000), 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 curie measurement to becquerels for a spec, listing, or report.
- Checking curie↔becquerel figures while comparing products, datasets, or documentation.
- Learning the curie-to-becquerel relationship from the worked formula and the common-value table.
Frequently asked questions
How many becquerels are in a curie?
One curie is 37000000000 becquerels. Multiply the curie value by 37000000000 to convert. For example, 10 Ci = 370000000000 Bq.
What is the formula to convert curies to becquerels?
Bq = Ci × 37000000000. This tool applies it automatically and shows a worked example: 10 Ci = 370000000000 Bq.
Can it convert becquerels back to curies?
Yes. Press the swap button, or type into the becquerel field, and the tool converts becquerels to curies using the inverse of the same relationship.
Is the conversion accurate?
It uses the standard radioactivity definition (Bq = Ci × 37000000000), 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.
