Area Measurement Systems
Metric System
- Square Meter (m²) - The SI base unit of area, equal to a square with 1 meter sides
- Hectare (ha) - Equal to 10,000 m², commonly used for land measurement
- Square Kilometer (km²) - 1 million m², used for large territories and countries
- Are (a) - 100 m², used in some European countries
Imperial System
- Square Foot (ft²) - 0.0929 m², standard in US real estate
- Acre - 43,560 ft² (about 0.4 hectares), traditional land measurement
- Square Mile (mi²) - 640 acres, used for large areas like cities
- Square Yard (yd²) - 9 ft², used in some construction measurements
Regional Units
- Bigha - Varies by region (India: 0.25-1.6 acres, Nepal: 1.67 acres)
- Pyeong - ~3.3 m², standard unit in Korean real estate
- Feddan - ~4,200 m², traditional Egyptian unit
- Dunam - ~1,000 m², used in Middle Eastern countries
- Tatami - ~1.65 m², Japanese room measurement
Area Conversion FAQs
How do I convert between metric and imperial area units?
Our converter handles all conversions automatically. For manual calculations:
- 1 square meter = 10.764 square feet
- 1 hectare = 2.471 acres
- 1 square kilometer = 0.386 square miles
Why are there different area measurement systems?
Different systems developed historically in different regions. The metric system was developed during the French Revolution for standardization, while imperial units evolved from older English units. Regional units often relate to practical measurements (like how much land a team of oxen could plow in a day).
How accurate are the conversions?
Our conversions use precise mathematical relationships between units. For regional units with variable definitions (like bigha), we use the most common standardized values. All calculations are performed with high precision floating-point arithmetic.
Did You Know?
The acre was originally defined as the area of land that could be plowed in one day with a yoke of oxen. This historical definition explains why it's not a round number in any modern measurement system.
