The conversion from square feet to square meters is a fundamental unit conversion in the metric system. Square feet (SF) is an imperial area unit commonly used in the United States, while square meters (m²) is the standard metric unit for area measurement used internationally.
The conversion uses the formula:
Where:
Explanation: One square foot equals exactly 0.09290304 square meters. This conversion factor is derived from the relationship between feet and meters (1 foot = 0.3048 meters).
Details: Accurate area conversion is essential for international real estate transactions, construction projects, architectural planning, and scientific research where metric units are required. It ensures consistency and precision in measurements across different measurement systems.
Tips: Enter the area value in square feet. The value must be a non-negative number. The calculator will automatically convert it to square meters with high precision.
Q1: Why is the conversion factor 0.09290304?
A: This exact value comes from the definition that 1 foot = 0.3048 meters exactly. Since area conversion involves squaring the linear conversion, (0.3048)^2 = 0.09290304.
Q2: How accurate is this conversion?
A: The conversion is mathematically exact based on the defined relationship between feet and meters in the international system of units.
Q3: When would I need to convert square feet to square meters?
A: Common situations include international property comparisons, scientific research papers, engineering projects in metric countries, and any context where metric units are required.
Q4: Are there any rounding conventions?
A: For most practical purposes, rounding to 2-4 decimal places is sufficient, though the calculator provides higher precision for accuracy.
Q5: Can I convert back from square meters to square feet?
A: Yes, the reverse conversion uses the formula: SF = m² ÷ 0.09290304 or SF = m² × 10.7639104167
