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 Foot (US Survey)

The square foot (US survey) is a unit of area based on the US survey foot, which is slightly longer than the international foot. It is mainly used in land surveying and mapping in the United States.

• 
  

  1 US survey foot = 1200⁄3937 meters (approximately 0.3048006096 m)
