Enter an area value to convert between units
This free area converter instantly switches a two-dimensional measurement between square meters, square kilometers, hectares, square feet, square yards, acres and square miles. Type in a value, choose the unit it is currently measured in, and the calculator returns that same area expressed in every other supported unit at once — no manual multiplication, no lookup charts, and no risk of a misplaced decimal point. It runs entirely in your browser, so nothing you enter is ever uploaded or stored.
Enter any positive number and select its starting unit — say, 2,000 square feet or 5 acres — and the converter multiplies that value by the unit's conversion factor to find the equivalent area in square meters, then divides by every other unit's factor to build a complete results table. The output covers both the metric units used across most of the world (square meters, hectares, square kilometers) and the imperial / US customary units still common in the United States, the United Kingdom, and several other countries (square feet, square yards, acres, square miles).
Real estate agents and home buyers use it to compare a listing's floor area in square feet against a similar property advertised in square meters. Farmers, ranchers, and agricultural buyers convert between acres and hectares to size up land purchases or crop yields per unit area. Construction contractors, landscapers, and flooring or carpet installers use it to convert plan dimensions into the units their materials are priced in. Architects and civil engineers move between metric and imperial drawings, students and teachers use it to check geometry and land-use homework, and international property investors rely on it to evaluate listings across countries that use different measurement systems.
A small conversion error compounds quickly with area, because area scales with the square of any linear error. Getting a unit conversion wrong when quoting flooring, paint, sod, or fencing can mean ordering the wrong quantity of materials or misjudging a property's true size relative to comparable listings. Using a converter built on standard, internationally recognized conversion factors removes that risk and keeps every comparison — whether it's a 5-acre farm plot or a 200-square-meter apartment — on the same footing.
Beyond real estate and agriculture, area conversion comes up constantly in everyday planning: sizing a solar panel array in square feet versus a manufacturer's square meter spec sheet, comparing sports-field dimensions across countries, working out how many hectares a national park covers in square miles, or converting a room's square footage before buying tile, carpet, or paint by the square meter. This calculator is built to handle all of these cases with the same seven-unit table.
The exact conversion factors this Area Converter uses, and why area units are squared
Area measures length × width, so it is always expressed in "square" units — the unit itself is squared, not just scaled.
Because area equals length times width, converting area units means squaring the linear conversion factor, not using it directly.
The converter bridges SI metric units (m², km², hectare) and imperial / US customary units (ft², yd², acre, mi²) in one results table.
Why the factors are squared, not linear: a linear (one-dimensional) conversion, such as feet to meters, uses a single multiplier: 1 ft = 0.3048 m. Area, however, is two-dimensional — it is length multiplied by width. So converting 1 square foot to square meters requires squaring that same linear factor: 1 ft² = 0.3048 m × 0.3048 m = 0.3048² m² = 0.092903 m². The same logic applies to every unit in the table: 1 yd = 0.9144 m, so 1 yd² = 0.9144² = 0.836127 m²; 1 mile = 1,609.344 m, so 1 mi² = 1,609.344² = 2,589,988.11 m². This is why doubling a length quadruples the area, and why area conversion factors are always the square of the equivalent linear conversion factor.
These conversion factors follow the exact linear-unit definitions published by the U.S. National Institute of Standards and Technology (NIST) and the International System of Units (SI) maintained by the BIPM (Bureau International des Poids et Mesures), which is why the same figures — 0.3048 m per foot, 0.9144 m per yard, 1,609.344 m per mile — appear consistently across government, scientific, and engineering references worldwide.
| Unit | Group | Symbol | Equivalent in Square Meters (m²) |

| Square Kilometer | Metric | km² | 1,000,000 |
| Hectare | Metric | ha | 10,000 |
| Square Foot | Imperial / US | ft² | 0.092903 |
| Square Yard | Imperial / US | yd² | 0.836127 |

Convert any area value into square meters, hectares, acres, and more in five steps
Type the number you want to convert into the Value field, such as 2000 or 5.
Choose the unit your value is currently measured in from the From Unit dropdown — square feet, acres, hectares, or any of the seven supported units.
The converter multiplies your value by the unit's factor to find the equivalent area in square meters, then calculates every other unit from that base value.
Review the output table showing your value converted into square meters, square kilometers, hectares, square feet, square yards, acres and square miles — all at once.

Two realistic area conversions, worked out step by step
A home buyer sees a US real estate listing for a 2,000 square foot house and wants to compare it with square-meter listings abroad.
A farmer is comparing a 5-acre plot listed in the US against similar farmland priced per hectare.
| Step | Calculation | Value |
|---|---|---|
| 1. Convert acres to m² (base unit) | 5 × 4,046.86 | 20,234.3 m² |
| 2. Convert m² to hectares | 20,234.3 ÷ 10,000 | 2.0234 ha |
| 3. Convert m² to square feet (for reference) | 20,234.3 ÷ 0.092903 | 217,800 ft² |
Result: 5 acres equals approximately 2.02 hectares, confirming the well-known reference figure that 1 acre ≈ 0.4047 hectares.
What the output table means and how area units are used around the world
Once you click Convert, the results table shows your entered area expressed in all seven supported units at the same time, with the unit you started from highlighted. Each row is mathematically equivalent to the others — 185.81 m², 0.01858 ha, and 222.22 yd² all describe the exact same physical area, just in different units.
The United States overwhelmingly uses square feet for homes and acres for land and farms. The United Kingdom mixes square feet for indoor property listings with acres and hectares for land. Most of Europe, Latin America, and Asia use square meters for homes and hectares for agricultural and forest land, following the metric system endorsed by the SI. Countries such as India and Pakistan also use acres for larger rural plots alongside local units like bigha or gunta, which fall outside this calculator's seven standard units.
