Common Scenarios
Area conversion is crucial in real estate, land planning, and agriculture. In China, "square meters" are used for housing, while in Western countries, "square feet" or "acres" are common. For agricultural land, Chinese farmers often use "mu" and "hectares".
History & Background
Area is the two-dimensional extension of length. Ancient agricultural societies relied heavily on land, so early area units were related to farming labor. The word "Acre" literally means "field" and was the amount of land a yoke of oxen could plow in one day.
Conversion Details
Area conversion is based on the square meter (m²).
Common conversions: 1 hectare = 10,000 m², 1 acre ≈ 4,046.86 m², 1 mu ≈ 666.67 m².
