About this tool
Convert meters to astronomical units instantly. Free, bidirectional, and fully in-browser.
1 meter equals 6.684587e-12 astronomical units — enter any meter value to convert it to astronomical units instantly. This Meter to Astronomical unit converter is a client-side tool: it applies a single multiplication (AU = m × 6.684587e-12) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert astronomical units back to meters. A reference table lists common meter values already converted, and nothing you enter is sent to a server.
Open Meter to Astronomical unit Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Meter field.
Read the equivalent in astronomical units in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert astronomical units to meters.
The result updates as you type, and the swap button flips the conversion to astronomical unit → meter without reloading.
The conversion uses the precise factor (AU = m × 6.684587e-12), 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 meter is 6.684587e-12 astronomical units. Multiply the meter value by 6.684587e-12 to convert. For example, 10 m = 6.684587e-11 AU.
AU = m × 6.684587e-12. This tool applies it automatically and shows a worked example: 10 m = 6.684587e-11 AU.
Yes. Press the swap button, or type into the astronomical unit field, and the tool converts astronomical units to meters using the inverse of the same relationship.
It uses the standard distance and length definition (AU = m × 6.684587e-12), 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.
