About this tool
Convert astronomical units to furlongs instantly. Free, bidirectional, and fully in-browser.
1 astronomical unit equals 743646458.2 furlongs — enter any astronomical unit value to convert it to furlongs instantly. This Astronomical unit to Furlong converter is a client-side tool: it applies a single multiplication (fur = AU × 743646458.2) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert furlongs 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 Furlong 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 furlongs in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert furlongs to astronomical units.
The result updates as you type, and the swap button flips the conversion to furlong → astronomical unit without reloading.
The conversion uses the precise factor (fur = AU × 743646458.2), 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.
