About this tool
Convert ampere-hours to milliampere-hours instantly. Free, bidirectional, and fully in-browser.
1 ampere-hour equals 1000 milliampere-hours — enter any ampere-hour value to convert it to milliampere-hours instantly. This Ampere-hour to Milliampere-hour converter is a client-side tool: it applies a single multiplication (mAh = Ah × 1000) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert milliampere-hours back to ampere-hours. A reference table lists common ampere-hour values already converted, and nothing you enter is sent to a server.
Open Ampere-hour to Milliampere-hour Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Ampere-hour field.
Read the equivalent in milliampere-hours in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert milliampere-hours to ampere-hours.
The result updates as you type, and the swap button flips the conversion to milliampere-hour → ampere-hour without reloading.
The conversion uses the precise factor (mAh = Ah × 1000), so the number matches a manual calculation to the decimal places you choose.
A slider sets 0–10 decimal places, and very small or very large results switch to scientific notation instead of rounding to zero.
Everything runs locally in your browser — no upload, no account, no limit on conversions.
One ampere-hour is 1000 milliampere-hours. Multiply the ampere-hour value by 1000 to convert. For example, 10 Ah = 10000 mAh.
mAh = Ah × 1000. This tool applies it automatically and shows a worked example: 10 Ah = 10000 mAh.
Yes. Press the swap button, or type into the milliampere-hour field, and the tool converts milliampere-hours to ampere-hours using the inverse of the same relationship.
It uses the standard electric charge definition (mAh = Ah × 1000), not a rounded approximation, so results are exact to the number of decimal places you select.
Yes. The converter is a browser-side script with no network calls: your values are never uploaded, and once the page has loaded it keeps working without a connection.
