femtocoulomb to gigacoulomb
Convert femtocoulomb (fC) to gigacoulomb (GC). Use an editable electric charge converter, conversion formula, and reference table.
1 fC = 1e-24 GC
Conversion formula
One femtocoulomb equals 1e-24 gigacoulomb. Multiply your value in femtocoulomb by this factor to get gigacoulomb. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 femtocoulomb:5 × 1e-24 = 5e-24 GC

About these measurements
Electric charge can be expressed in coulombs or ampere-hours.
The base reference used here is the coulomb. One femtocoulomb is 1e-15 base units; one gigacoulomb is 1,000,000,000 base units.
Important distinctions
Ampere-hours are charge, not energy. Battery voltage is needed to calculate watt-hours.
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 fC to GC?
Multiply the quantity in fC by 1e-24. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the gigacoulomb to femtocoulomb converter.
