Square Millimeter [mm²]
A square millimeter (mm²) is a unit of area equal to a square with sides 1 millimeter long. It is used to measure very small surfaces, such as parts of mechanical components or electronic circuits.
1 mm² = 0.000001 m².
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.
