Area Converter

Overview

What is a Area Converter?

> Area Converter turns any area between metric, imperial, and land units — square metres, square feet, acres, hectares, and square miles. Enter a value, pick your units, and read the result with the exact factor shown (1 acre = 43,560 sq ft ≈ 4046.86 m²; 1 m² = 10.764 sq ft). It works offline. ---

### H2: Convert area between metric, imperial, and land units

Area conversions turn up whenever space is involved — a floor plan in square metres you want in square feet, a plot of land quoted in acres, or a farm measured in hectares. This converter covers the units people actually use: square metre, square centimetre, square millimetre, square kilometre, and hectare on the metric side, and square inch, square foot, square yard, acre, and square mile on the imperial and land side.

Type a value, choose what you're converting *from* and *to*, and the answer appears instantly, with a swap button and an all-units table that shows every unit at once. Every result comes with the exact factor used, so you can verify it.

There's one thing about area that trips people up, and the tool is built to prevent it: area factors are the square of length factors. One foot is 0.3048 metres, so one square foot is 0.3048², which is 0.09290304 m² — not 0.3048. Converting area with the linear factor is a classic mistake, and stating the squared factor stops it.

The land units are where this converter earns its keep. An acre is 43,560 square feet (about 4046.86 m²) — and it's a land area, not a fixed square shape, so it can be any outline. A hectare is a clean 10,000 m². The two get confused often, so it's worth remembering that one hectare is about 2.471 acres, and a square mile is 640 acres.

If you also need to convert the sides of a shape, use the Length Converter; for capacities, the Volume Converter. Everything here runs on your own device using fixed factors, so there's nothing to upload and no connection needed once the page has loaded.

Guide

How to use the Area Converter

Step 1: Enter your value. Type the area you want to convert into the input box

Decimals are fine.

Step 2: Pick the "from" unit. Choose the unit your number is currently in — for example, square feet (ft²)

Pick the "from" unit. Choose the unit your number is currently in — for example, square feet (ft²).

Step 3: Pick the "to" unit. Choose the unit you want the answer in — for example, square metres (m²)

The result updates instantly.

Step 4: Read the result and the factor. The converted value appears with the exact relationship used (for example, 1 ft² = 0.09290304 m²), so you can verify it

Read the result and the factor. The converted value appears with the exact relationship used (for example, 1 ft² = 0.09290304 m²), so you can verify it.

Step 5: Copy, swap, or expand. Use Copy to grab the number, the swap button to reverse the direction, or open the all-units table to see your value in every unit at once

Adjust the decimal places for more precision.

Frequently Asked Questions

How many square feet are in a square meter?

One square metre is 10.7639 square feet. This comes from squaring the length factor: one metre is 3.28084 feet, and 3.28084² = 10.7639. So a 50 m² room is about 538 ft². To go the other way, one square foot is 0.092903 m². The tool shows this exact factor with every result.

---

How do I convert square feet to square meters?

Multiply square feet by 0.092903. That's the *square* of the foot-to-metre factor (0.3048² = 0.09290304), because area scales with the square of length. For example, 500 ft² × 0.092903 = 46.45 m². To reverse it, multiply square metres by 10.7639. The tool applies the squared factor automatically, so you don't have to remember it.

---

How many square feet are in an acre?

Exactly 43,560 square feet. An acre is defined as 43,560 ft², which works out to about 4046.86 square metres. It's a unit of land area, historically the amount a pair of oxen could plough in a day. So a half-acre plot is 21,780 ft². Enter any value and the tool converts acres to square feet, metres, or hectares.

---

How big is an acre, really?

An acre is 43,560 square feet, or about 4047 square metres — roughly the size of a standard football (soccer) pitch without the run-off, or about 60% of an American football field. It's a *land area*, not a fixed shape, so it can be a square (about 208.7 ft on a side), a long strip, or any outline that adds up to 43,560 ft².

---

How many acres are in a hectare?

One hectare is about 2.47105 acres. A hectare is a clean 10,000 square metres, while an acre is 4046.86 m², so a hectare is roughly two and a half acres. Going the other way, one acre is about 0.4047 hectares. These two land units are easy to mix up, so the tool keeps them separate and shows the factor.

---

What's the difference between an acre and a hectare?

They're both land-area units from different systems. An acre (4046.86 m², or 43,560 ft²) comes from the imperial system and is common in the US, UK, and India. A hectare (10,000 m² exactly) is the metric land unit used almost everywhere else. A hectare is about 2.47 acres — noticeably bigger — so never treat them as equal when comparing plots.

---

Why is area conversion different from length conversion?

Because area is two-dimensional, its conversion factor is the *square* of the length factor. One foot is 0.3048 metres, but one square foot is 0.3048 × 0.3048 = 0.0929 square metres. Using the linear factor (0.3048) for area is a common mistake that makes results about 3.3 times too big. The tool shows the correct squared factor to prevent this.

---

How many square meters are in a hectare?

Exactly 10,000 square metres. A hectare is defined as the area of a 100 m × 100 m square, which is 10,000 m² — that's what makes it such a tidy metric land unit. A square kilometre, by comparison, is 100 hectares (1,000,000 m²). Enter hectares in the tool and it converts to square metres, acres, or any other area unit.

---

How many acres are in a square mile?

Exactly 640 acres. A square mile is 640 acres, or 2,589,988 square metres (about 2.59 km²). This is why rural land in the US is often described in "sections" — a section is one square mile, or 640 acres. So a quarter-section is 160 acres. The tool handles square miles alongside acres, hectares, and metric units.

---

Is this converter exact, or does it round the answer?

The math is exact — it uses defined factors (1 acre = 4046.8564224 m², 1 hectare = 10,000 m², 1 ft² = 0.09290304 m²). Only the *displayed* value is rounded for readability, and you can add decimal places for more precision. The factor shown with each result lets you verify the figure yourself.

---

What's the formula to convert area units?

Convert everything through square metres. Multiply your value by its factor to m² (square foot → ×0.09290304, acre → ×4046.8564, hectare → ×10,000), then divide by the target unit's factor. For square feet to square metres it's simply value × 0.092903. Remember these factors are the squares of the matching length factors. The tool applies this for any pair.

---

Does the tool work offline, and does it upload my data?

It works fully offline once the page has loaded, and it never uploads anything. All conversions are pure arithmetic using fixed factors, so the calculation happens on your own device — no server, no account, no tracking. That makes it dependable on site with no signal, and private by design, since there's nothing to send anywhere.
