Square Chain [ch²]


A square chain (ch²) is a unit of area used in land surveying, especially in the US and UK. It represents the area of a square with sides one chain long.



  • 1 chain = 66 feet (20.1168 meters)



  • 1 square chain = 66 ft × 66 ft = 4,356 square feet ≈ 404.69 m²



  • 10 square chains = 1 acre



Square chains are used to measure land parcels and agricultural fields.

Square Nanometer [nm²]


A square nanometer (nm²) is a unit of area equal to a square with sides 1 nanometer long (1 nm = 1 billionth of a meter, or 10⁻⁹ m).

It’s used to measure extremely tiny areas, like the surface of molecules or nanomaterials.

1 nm² = 1 × 10⁻¹⁸ m².
