A slider sets 0–10 decimal places, and very small or very large results switch to scientific notation instead of rounding to zero.

Frequently asked questions
How many hectares are in a square kilometer?
One square kilometer is 100 hectares. Multiply the square kilometer value by 100 to convert. For example, 10 km² = 1000 ha.
What is the formula to convert square kilometers to hectares?
ha = km² × 100. This tool applies it automatically and shows a worked example: 10 km² = 1000 ha.
Can it convert hectares back to square kilometers?
Yes. Press the swap button, or type into the hectare field, and the tool converts hectares to square kilometers using the inverse of the same relationship.
Is the conversion accurate?
It uses the standard area definition (ha = km² × 100), not a rounded approximation, so results are exact to the number of decimal places you select.
Does this work offline and stay private?
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.
