femtobecquerel to nanobecquerel
Convert femtobecquerel (fBq) to nanobecquerel (nBq). Use an editable radioactivity converter, conversion formula, and reference table.
1 fBq = 0.000001 nBq
Conversion formula
One femtobecquerel equals 0.000001 nanobecquerel. Multiply your value in femtobecquerel by this factor to get nanobecquerel. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 femtobecquerel:5 × 0.000001 = 0.000005 nBq

About these measurements
Activity measures nuclear decays per second.
The base reference used here is the becquerel. One femtobecquerel is 1e-15 base units; one nanobecquerel is 1e-9 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
