Convert area instantly — type a value, pick your units, and every other common unit updates live below. 100% free, runs entirely in your browser, no sign-up.
Every unit below updates live from the value you enter in the "From" field above.
Because area is length squared, its conversion factors are the square of the equivalent length factors — a foot is 0.3048 meters, so a square foot is 0.3048² ≈ 0.0929 square meters. The acre is the odd one out: it's a historical land-measurement unit (originally the area a yoke of oxen could plow in a day) rather than a clean multiple of any other unit here.
Yes. It's completely free with no sign-up, and every conversion runs locally in your browser via JavaScript — the numbers you type are never sent to our servers.
Each unit uses its standard, internationally defined conversion factor, calculated in full precision and only rounded for display. Results are accurate to at least 6 significant figures.
This page intentionally covers the most commonly used area units rather than an exhaustive engineering list. Use the suggestion button in the bottom-right corner of any page to request a unit and we'll consider adding it.
