About Acre (US Survey) (ac (US))
Definition
The US survey acre is a historical unit of area based on the US survey foot, equal to approximately 4,046.873 m².
Mathematical Relationship
1 US survey acre ≈ 4,046.873 m². Differs from international acre (4,046.856 m²) by about 0.016 m².
Conversion Formula
To convert US survey acres to m²: multiply by 4,046.873. To international acres: multiply by ~1.000004.
Practical Applications
Historical US land surveys, old property deeds, and State Plane Coordinate System calculations.
Interesting Facts
The difference between US survey and international acre is about 0.016 m² — roughly the area of a sheet of paper. Over large areas, it adds up.
Common Mistakes
Using US survey acre in new calculations — it's been deprecated since 2023. Use the international acre instead.
Educational Tips
As of 2023, the US survey foot and acre are retired. All US measurements now use the international definitions.
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.
