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.
Varas Conuqueras Cuadradas
The term varas conquereñas (or varas conquenses) refers to a traditional Spanish unit of length used in some regions, and varas conquereñas cuadradas means square varas conquereñas, a unit of area.
1 vara conquereña ≈ 0.8382 meters
1 square vara conquereña = (0.8382 m)² ≈ 0.7025 m²
This unit was historically used in certain parts of Spain and Spanish colonies for land measurement. Like other traditional units, it is largely replaced by metric units today but may still appear in old documents.
