curie to petabecquerel
Convert curie (Ci) to petabecquerel (PBq). Use an editable radioactivity converter, conversion formula, and reference table.
1 Ci = 0.000037 PBq
Conversion formula
One curie equals 0.000037 petabecquerel. Multiply your value in curie by this factor to get petabecquerel. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 curie:5 × 0.000037 = 0.000185 PBq

About these measurements
Activity measures nuclear decays per second.
The base reference used here is the becquerel. One curie is 37,000,000,000 base units; one petabecquerel is 1e+15 base units.
Important distinctions
Activity is not absorbed dose or equivalent dose. This is a unit tool, not an exposure assessment.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert Ci to PBq?
Multiply the quantity in Ci by 0.000037. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the petabecquerel to curie converter.
