Why this tool is useful
Use this converter when a radioactivity value is supplied in megabecquerels, while a specification, worksheet or report requires curies.

Megabecquerels to Curies Converter
Convert megabecquerels (MBq) to curies (Ci) with a transparent radioactivity base-unit calculation.
Ready. Your working data stays in this browser.
How it works
The browser multiplies MBq by 1e+06 to reach the shared SI reference, then divides by 3.7e+10 to return Ci. No value leaves the page.
Practical example
Entering 1 MBq returns 2.7027027027e-05 Ci; the page also shows the exact factors used for an independent check.
Validation
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Privacy boundary
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Result passport
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
