Area Converter
Type an area into any one unit and every other unit updates at the same time. Square meters, square feet, acres, hectares, and East Asian property units (mu, tsubo, ping) — all on one live page. No convert button, no sign-up, and nothing you type ever leaves your browser.
What is the Area Converter?
The Area Converter is a free, instant tool for turning one area measurement into every other unit at once. Type a value into any field — square meters, square feet, square kilometers, square miles, square yards, square inches, square centimeters, acres, or hectares — and the rest update live as you type. It also handles the East Asian property units that most Western converters leave out: the Chinese mu (亩), the Japanese and Korean tsubo (坪), and the Taiwanese ping (平). That makes it the simplest way to compare a piece of land or a home across countries without opening three separate calculators.
How to use it
- Pick the unit you already know and type the number into its box (for example, 60 into square meters).
- Read the answer instantly in every other unit — no Convert button, no page reload.
- Need the reverse? Type into the field for the unit you want to start from instead; the tool is fully multi-directional.
- Copy the value you need and you are done. Nothing is saved, nothing is uploaded — use it and move on.
The method behind it
Every unit is anchored to one base: the square meter (m²). The tool converts your input to square meters, then scales out to each target unit using fixed, internationally accepted factors:
- 1 m² = 10.7639 sq ft = 0.0001 hectares = 0.000247105 acres
- 1 acre = 4,046.86 m² = 0.404686 hectares
- 1 hectare = 10,000 m² = 2.47105 acres
- 1 sq mi = 2,589,988 m² = 640 acres
- 1 sq yd = 0.836127 m²; 1 sq in = 0.00064516 m²
- 1 mu (亩) = 666.667 m²; 1 tsubo (坪) = ping (平) = 3.30579 m²
Because everything routes through a single base unit, all displayed values stay consistent with each other. Results are rounded only for readability — the underlying math uses full-precision factors.

| Square meters | Square feet | Acres | Hectares | Mu (亩) |
|---|---|---|---|---|
| 1 m² | 10.7639 | 0.000247 | 0.0001 | 0.0015 |
| 10 m² | 107.6391 | 0.002471 | 0.001 | 0.015 |
| 50 m² | 538.1955 | 0.012355 | 0.005 | 0.075 |
| 100 m² | 1,076.39 | 0.024711 | 0.01 | 0.15 |
| 500 m² | 5,381.96 | 0.123553 | 0.05 | 0.75 |
| 1,000 m² | 10,763.91 | 0.247105 | 0.1 | 1.5 |
| 4,046.86 m² | 43,560 | 1 | 0.404686 | 6.0703 |
| 10,000 m² | 107,639.1 | 2.4711 | 1 | 15 |
Examples
- A 60 m² mainland-China flat = 645.8 sq ft ≈ 18.15 tsubo — handy when comparing with a Hong Kong listing quoted in square feet.
- 1 acre of US land = 4,046.86 m² = 0.4047 hectares = 6.07 mu.
- 5 hectares of farmland = 12.36 acres = 75 mu = 50,000 m².
Common use cases
- Cross-region home buying: read a mainland-China 平方米 listing in Hong Kong or US square feet, or check a Japanese listing quoted in tsubo.
- Land and farming: convert acres or hectares to mu when valuing agricultural plots.
- Architecture and interior design: move floor areas between metric and imperial drawings.
- Real-estate and relocation research: sanity-check listing sizes when moving between countries.
- Students and quick homework checks: verify area-unit conversions in one glance.
Why use this one
Most online area converters only swap two units at a time and skip East Asian property units entirely. This tool shows all units simultaneously, includes mu, tsubo, and ping, runs 100% in your browser (your numbers never leave your device), needs no sign-up, and stays fast and ad-light so you get the answer in well under a second.
Frequently asked questions
How many square feet is one square meter?
One square meter is about 10.7639 square feet. In Hong Kong real estate a flat's 平方米 figure is multiplied by roughly 10.76 to read it in the locally quoted square feet, so a 60 m² flat is about 645.8 sq ft.
How many square meters is one mu (亩)?
One Chinese mu (亩) equals about 666.67 square meters, or roughly 0.1647 acres. So 1 acre is about 6.07 mu, and 1 hectare (10,000 m²) is about 15 mu.
How many square meters is one tsubo (坪) or ping (平)?
One tsubo (坪, used in Japan and Korea) and one Taiwanese ping (平) both equal about 3.306 square meters, which is roughly 35.58 square feet. They share the same definition, so 30 tsubo is about 99.2 m².
How do I convert acres to hectares?
Multiply acres by 0.404686 to get hectares, or divide hectares by 0.404686 to go back. One acre is about 0.4047 hectares and one hectare is about 2.4711 acres.
Does this area converter send my numbers anywhere?
No. Every conversion runs entirely in your browser with JavaScript. Nothing you type is uploaded to a server, and the tool keeps working even after you go offline once the page has loaded.
