About this tool
Convert astronomical units to nautical miles instantly. Free, bidirectional, and fully in-browser.
1 astronomical unit equals 80776388.07 nautical miles — enter any astronomical unit value to convert it to nautical miles instantly. This Astronomical unit to Nautical mile converter is a client-side tool: it applies a single multiplication (nmi = AU × 80776388.07) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert nautical miles back to astronomical units. A reference table lists common astronomical unit values already converted, and nothing you enter is sent to a server.
Open Astronomical unit to Nautical mile Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Astronomical unit field.
Read the equivalent in nautical miles in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert nautical miles to astronomical units.
The result updates as you type, and the swap button flips the conversion to nautical mile → astronomical unit without reloading.
The conversion uses the precise factor (nmi = AU × 80776388.07), 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 astronomical unit is 80776388.07 nautical miles. Multiply the astronomical unit value by 80776388.07 to convert. For example, 10 AU = 807763880.7 nmi.

Yes. Press the swap button, or type into the nautical mile field, and the tool converts nautical miles to astronomical units using the inverse of the same relationship.
It uses the standard distance and length definition (nmi = AU × 80776388.07), 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.
