How to use it
- Type the value in the millicuries box.
- Read the result in megabecquerels as you type, and pick the precision you need.
- Swap the direction to convert back, or copy the result.
How it is calculated
MBq = mCi × 37
Multiply the value in millicuries by 37 to get megabecquerels.
Example
To convert 25 mCi to megabecquerels: 25 × 37 = 925 MBq.

About the units
- Millicurie
- A millicurie is one thousandth of a curie, exactly 37 megabecquerels, used for radiopharmaceutical doses.
- Megabecquerel
- A megabecquerel is exactly one million becquerels, the usual SI unit for diagnostic radiopharmaceutical doses.
Limits and caveats
- Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).
- Both unit factors are exact by their official definitions.
Questions about this tool
How many megabecquerels are in one millicurie?
1 mCi = 37 MBq exactly.
How do I convert millicuries to megabecquerels?
Use MBq = mCi × 37. For example, 25 mCi = 925 MBq.
How many millicuries are in one megabecquerel?
1 MBq = 0.027027 mCi.
Why is a curie 3.7 × 10^10 becquerels?
The curie was first based on the activity of one gram of radium-226, then fixed at exactly 3.7 × 10^10 decays per second.
Is a becquerel the same as a hertz?
Both equal one per second, but the SI reserves the becquerel for radioactive decay and the hertz for periodic phenomena.
