microbecquerel to gigabecquerel
Convert microbecquerel (μBq) to gigabecquerel (GBq). Use an editable radioactivity converter, conversion formula, and reference table.
1 μBq = 1e-15 GBq
Conversion formula
One microbecquerel equals 1e-15 gigabecquerel. Multiply your value in microbecquerel by this factor to get gigabecquerel. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 microbecquerel:5 × 1e-15 = 5e-15 GBq

About these measurements
Activity measures nuclear decays per second.
The base reference used here is the becquerel. One microbecquerel is 0.000001 base units; one gigabecquerel is 1,000,000,000 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 μBq to GBq?
Multiply the quantity in μBq by 1e-15. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the gigabecquerel to microbecquerel converter.
