About this tool
Convert milliampere-hours to coulombs instantly. Free, bidirectional, and fully in-browser.
1 milliampere-hour equals 3.6 coulombs — enter any milliampere-hour value to convert it to coulombs instantly. This Milliampere-hour to Coulomb converter is a client-side tool: it applies a single multiplication (C = mAh × 3.6) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert coulombs back to milliampere-hours. A reference table lists common milliampere-hour values already converted, and nothing you enter is sent to a server.
Open Milliampere-hour to Coulomb Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Milliampere-hour field.
Read the equivalent in coulombs in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert coulombs to milliampere-hours.
The result updates as you type, and the swap button flips the conversion to coulomb → milliampere-hour without reloading.
The conversion uses the precise factor (C = mAh × 3.6), 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 milliampere-hour is 3.6 coulombs. Multiply the milliampere-hour value by 3.6 to convert. For example, 10 mAh = 36 C.
C = mAh × 3.6. This tool applies it automatically and shows a worked example: 10 mAh = 36 C.
Yes. Press the swap button, or type into the coulomb field, and the tool converts coulombs to milliampere-hours using the inverse of the same relationship.
It uses the standard electric charge definition (C = mAh × 3.6), 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.
