About this tool
Convert millicuries to curies instantly. Free, bidirectional, and fully in-browser.
1 millicurie equals 0.001 curies — enter any millicurie value to convert it to curies instantly. This Millicurie to Curie converter is a client-side tool: it applies a single multiplication (Ci = mCi × 0.001) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert curies back to millicuries. A reference table lists common millicurie values already converted, and nothing you enter is sent to a server.
Open Millicurie to Curie Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Millicurie field.
Read the equivalent in curies in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert curies to millicuries.
The result updates as you type, and the swap button flips the conversion to curie → millicurie without reloading.
The conversion uses the precise factor (Ci = mCi × 0.001), so the number matches a manual calculation to the decimal places you choose.
A slider sets 0–10 decimal places, and very small or very large results switch to scientific notation instead of rounding to zero.
Everything runs locally in your browser — no upload, no account, no limit on conversions.
One millicurie is 0.001 curies. Multiply the millicurie value by 0.001 to convert. For example, 10 mCi = 0.01 Ci.
Ci = mCi × 0.001. This tool applies it automatically and shows a worked example: 10 mCi = 0.01 Ci.
Yes. Press the swap button, or type into the curie field, and the tool converts curies to millicuries using the inverse of the same relationship.
It uses the standard radioactivity definition (Ci = mCi × 0.001), not a rounded approximation, so results are exact to the number of decimal places you select.
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.
