About this tool
Convert ares to hectares instantly. Free, bidirectional, and fully in-browser.
1 are equals 0.01 hectares — enter any are value to convert it to hectares instantly. This Are to Hectare converter is a client-side tool: it applies a single multiplication (ha = a × 0.01) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert hectares back to ares. A reference table lists common are values already converted, and nothing you enter is sent to a server.
Open Are to Hectare Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Are field.
Read the equivalent in hectares in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert hectares to ares.
The result updates as you type, and the swap button flips the conversion to hectare → are without reloading.
The conversion uses the precise factor (ha = a × 0.01), 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 are is 0.01 hectares. Multiply the are value by 0.01 to convert. For example, 10 a = 0.1 ha.
ha = a × 0.01. This tool applies it automatically and shows a worked example: 10 a = 0.1 ha.
Yes. Press the swap button, or type into the hectare field, and the tool converts hectares to ares using the inverse of the same relationship.
It uses the standard area definition (ha = a × 0.01), 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.
