ampere-hour to teracoulomb
Convert ampere-hour (Ah) to teracoulomb (TC). Use an editable electric charge converter, conversion formula, and reference table.
1 Ah = 3.6e-9 TC
Conversion formula
One ampere-hour equals 3.6e-9 teracoulomb. Multiply your value in ampere-hour by this factor to get teracoulomb. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 ampere-hour:5 × 3.6e-9 = 1.8e-8 TC

About these measurements
Electric charge can be expressed in coulombs or ampere-hours.
The base reference used here is the coulomb. One ampere-hour is 3,600 base units; one teracoulomb is 1e+12 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 Ah to TC?
Multiply the quantity in Ah by 3.6e-9. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the teracoulomb to ampere-hour converter.
