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 Centimeter (cm²)
Definition
The square centimeter is a metric unit of area equal to 0.0001 square meters, or the area of a square 1 cm on each side.
Mathematical Relationship
1 cm² = 0.0001 m² = 100 mm² ≈ 0.155 in². There are 10,000 cm² in 1 m².
Conversion Formula
To convert cm² to in²: multiply by 0.155. To m²: divide by 10,000. To mm²: multiply by 100.
Practical Applications
Wound sizes in medicine, postage stamp dimensions, fabric samples, phone screen sizes, and cross-sectional areas.
Interesting Facts
A US postage stamp is about 5 cm². The surface area of human skin is about 18,000 cm² (1.8 m²). A fingernail is about 1 cm².
Common Mistakes
Squaring incorrectly: 3 cm × 4 cm = 12 cm², not 12 cm. Units must be squared for area.
Educational Tips
Your fingernail is roughly 1 cm². A credit card is about 46 cm². These are easy visual references.
