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

About these measurements
Activity measures nuclear decays per second.
The base reference used here is the becquerel. One gigabecquerel is 1,000,000,000 base units; one microbecquerel is 0.000001 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 GBq to μBq?
Multiply the quantity in GBq 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 microbecquerel to gigabecquerel converter.
