About this tool
Convert milliamperes to amperes instantly. Free, bidirectional, and fully in-browser.
1 milliampere equals 0.001 amperes — enter any milliampere value to convert it to amperes instantly. This Milliampere to Ampere converter is a client-side tool: it applies a single multiplication (A = mA × 0.001) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert amperes back to milliamperes. A reference table lists common milliampere values already converted, and nothing you enter is sent to a server.
Open Milliampere to Ampere Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Milliampere field.
Read the equivalent in amperes in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert amperes to milliamperes.
The result updates as you type, and the swap button flips the conversion to ampere → milliampere without reloading.
The conversion uses the precise factor (A = mA × 0.001), 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 is 0.001 amperes. Multiply the milliampere value by 0.001 to convert. For example, 10 mA = 0.01 A.
A = mA × 0.001. This tool applies it automatically and shows a worked example: 10 mA = 0.01 A.
Yes. Press the swap button, or type into the ampere field, and the tool converts amperes to milliamperes using the inverse of the same relationship.
It uses the standard electric current definition (A = mA × 0.001), 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.
