Acre (US Survey) [ac]


The acre (US survey) is a unit of area used mainly in the United States for land measurement, based on the US survey foot. It is slightly different from the international acre due to the foot definition.



  • 1 US survey acre = 43,560 US survey square feet



  • 1 US survey acre ≈ 4,046.87261 square meters



  • Slightly larger than the international acre by about 0.0005%.



It is commonly used in land surveying, real estate, and agriculture.



Square Mil [mil²]


A square mil (mil²) is a very small unit of area used mainly in engineering and manufacturing, especially for measuring the cross-sectional area of wires and thin materials.



  • 1 mil = 1/1000 of an inch (0.001 inch)



  • 1 square mil = (0.001 inch)² = 0.000001 square inches (in²)



  • 1 square mil ≈ 6.4516 × 10⁻¹⁰ square meters (m²)



Square mils are useful for precise measurements in electronics and materials science.
