Microcurie to curie Conversion
1 microcurie (µCi) is equal to 0.000001 curie (Ci).
1 µCi = 0.000001 Ci
or
1 Ci = 1000000 µCi
Formula
To convert a radioactivity from microcurie (µCi) to curie (Ci), divide the radioactivity in microcurie by 1000000
r(Ci) = r(µCi) / 1000000
Examples:
Convert 1000 microcurie to curie:
r(Ci) = 1000µCi / 1000000 = 0.001 Ci

Frequently asked questions
How do I convert microcurie to curie?
Divide the value in microcurie by 1000000 to get the result in curie. For example, 5 µCi ÷ 1000000 = 5e-6 Ci.
How many curie are in 1 microcurie?
1 microcurie (µCi) is equal to 1e-6 curie (Ci).
How do I convert curie back to microcurie?
Use the inverse operation: multiply the value in curie by 1000000 to get the result in microcurie.
How accurate is the microcurie to curie conversion?
The converter multiplies by the conversion factor 1000000 and rounds the result to 9 decimal places by default. You can increase or reduce the precision with the digits option on this page.
