Ampere-hours to Milliampere-hours Converter
1 ampere-hour = 1,000 milliampere-hours
Charge, not energy. Converting mAh to watt-hours needs the battery voltage as well, so it is not a unit conversion.
1 ampere-hour equals 1,000 milliampere-hours
How to convert ampere-hours to milliampere-hours
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.
mAh = Ah × 1000One ampere-hour is 1000 milliampere-hours, so a single multiplication converts any value.
10,000 mAh = 10 × 1000Charge, not energy. Converting mAh to watt-hours needs the battery voltage as well, so it is not a unit conversion.

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.
