How It Works
Area converters work by expressing every unit as a multiple of a base unit — here, the square metre. Each unit has an exact factor: 1 square foot = 0.0929 m², 1 square yard = 0.8361 m², 1 acre = 4,046.86 m², 1 hectare = 10,000 m², and 1 square kilometre = 1,000,000 m². To convert, the value is multiplied by its from-unit factor to reach square metres, then divided by the to-unit factor. Note that area units square the underlying length relationship — since 1 metre = 3.28 feet, 1 square metre = 3.28² ≈ 10.76 square feet, not 3.28. This is a common source of error when converting by hand. Area conversion is essential in real estate (India often quotes land in acres, bigha, gunta, or square feet), agriculture (hectares and acres), and construction (square feet and square metres).
Formula
Result = value × (m² per from-unit) ÷ (m² per to-unit). Base unit: square metre. 1 acre = 4,046.86 m²; 1 hectare = 10,000 m².
Frequently Asked Questions
How many square feet are in a square metre?
About 10.76 square feet. Because area squares the length ratio (1 m = 3.28 ft), 1 m² = 3.28² ≈ 10.76 ft² — not 3.28.
How big is an acre?
An acre is 4,046.86 square metres, or about 43,560 square feet. A hectare is larger — 10,000 m² — so 1 hectare ≈ 2.47 acres.
What is the difference between an acre and a hectare?
Both measure land area. A hectare (10,000 m²) is metric and about 2.47 times larger than an acre (4,046.86 m²). Hectares are common in agriculture and official records; acres in real estate.
How do I convert square feet to square metres?
Multiply square feet by 0.0929. For example, a 1,000 sq ft flat = 1,000 × 0.0929 ≈ 92.9 m².
Why can't I use the length factor for area?
Area is two-dimensional, so you square the length conversion. 1 metre = 3.28 feet, but 1 square metre = 3.28² = 10.76 square feet. Forgetting to square is a frequent mistake this converter avoids.
