Square Kilometer [km²]

A square kilometer (km²) is a unit of area equal to a square that is 1 kilometer on each side. It is commonly used to measure large areas such as cities, countries, or large land plots.

1 km² = 1,000,000 m².

Circular Mil

A circular mil is a unit of area used mainly to measure the cross-sectional area of round wires and cables in electrical engineering.

• 
  

  Defined as the area of a circle with a diameter of 1 mil (1 mil = 0.001 inch).

  
  
• 
  

  Area = (diameter in mils)² circular mils.

  
  
• 
  

  1 circular mil ≈ 7.854 × 10⁻¹⁰ square meters or 0.7854 square mils.

  
  

Circular mils simplify calculations for round wires since area scales with the square of the diameter.
