Ampere-hours to Coulombs Converter
1 ampere-hour = 3,600 coulombs
1 ampere-hour equals 3,600 coulombs
How to convert ampere-hours to coulombs
Charge is current integrated over time: 1 Ah = 3600 C. Battery mAh is a charge rating; converting it to Wh additionally requires voltage and is not a charge-unit conversion.
C = Ah × 3600One ampere-hour is 3600 coulombs, so a single multiplication converts any value.
36,000 C = 10 × 3600Ampere-hours to coulombs conversion table

Sources and precision
Table results are rounded to 8 significant digits; formula constants may be rounded to 10. Worked example answers use 6 significant digits. The converter starts at 6 significant digits and lets you change display precision. Calculations use the stored factors without intermediate rounding. Exact unit definitions do not make an input measurement more precise; conventional and measured factors follow the assumptions stated here.
