How to Convert Square Foot (US Survey) to Square Meter
To convert US survey ft² to m²: multiply by 0.09290341. To international ft²: multiply by ~1.000004.
1 ft² (US) ≈ 0.09290341 m². Differs from international ft² (0.09290304 m²) by about 4 × 10⁻⁷ m².
For example, 1 Square Foot (US Survey) (ft² (US)) = 0.09290341161 Square Meter (m²).

About Square Foot (US Survey) (ft² (US))
Definition
The US survey square foot is a historical area unit based on the US survey foot (1200/3937 m), equal to approximately 0.09290341 m².
Mathematical Relationship
1 ft² (US) ≈ 0.09290341 m². Differs from international ft² (0.09290304 m²) by about 4 × 10⁻⁷ m².
Conversion Formula
To convert US survey ft² to m²: multiply by 0.09290341. To international ft²: multiply by ~1.000004.
Practical Applications
Historical property records and government land survey documents.
Interesting Facts
The difference from the international square foot is only about 0.4 mm² — negligible for a single measurement, but significant over millions of square feet.
Common Mistakes
Using the US survey foot in new work. Since 2023, only the international foot is valid in the US.
Educational Tips
The US survey foot existed because of a historical definition difference. It's now retired — use the international foot (exactly 0.3048 m).
About Square Meter (m²)
Definition
The square meter is the SI derived unit of area, equal to the area of a square with sides of exactly one meter.
Mathematical Relationship
1 m² = 10,000 cm² = 1,000,000 mm² = 10⁻⁶ km². Also: 1 m² ≈ 10.764 ft².
Conversion Formula
To convert m² to ft²: multiply by 10.764. To acres: divide by 4,046.86. To hectares: divide by 10,000.
Practical Applications
Room floor area, apartment sizes, garden plots, solar panel coverage, and building footprints.
Interesting Facts
A typical parking space is about 12 m². A standard tennis court is 260.87 m². A football (soccer) pitch is 7,140 m².
Common Mistakes
Confusing linear meters with square meters — doubling the side length quadruples the area, not doubles it.
Educational Tips
Imagine a square 1 m per side on the floor — that's 1 m². A single bed is roughly 1.8 m². Your room might be 10–15 m².
