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.

Square Mile (US Survey)

The square mile (US survey) is a unit of area used in the United States for land measurement based on the US survey foot. It represents a square with sides 1 mile long, where a mile is defined using the survey foot rather than the international foot.

1 US survey mile = 5,280 US survey feet

1 square mile (US survey) ≈ 2.589998 km² (slightly different from the international square mile of 2.59 km²)

This unit is mostly used in land surveying and mapping within the US.
