About these units
Sabin (sabin)
A sabin is the acoustic unit of sound absorption area, equivalent to the absorption provided by one square foot of a perfectly absorbing surface. Unlike geometric area units, the sabin measures how much sound energy a surface absorbs rather than its physical size alone. Materials with partial absorption effectiveness—such as acoustic tiles or drapes—contribute fractional sabins depending on their absorption coefficient. Architects and acoustic engineers use sabins to design theaters, concert halls, classrooms, and workplaces. The unit translates directly into reverberation time calculations, making it a foundational concept in architectural acoustics.
Varas Castellanas Cuad (v.c.c.)
A vara castellana cuadrada is the square form of the Castilian vara, an old Spanish unit of length. While the exact length of a vara historically ranged between regions, the commonly accepted Castilian value is 0.8359 meters. Thus, the square vara equals approximately 0.69875 square meters. Square varas were widely used in Spanish colonial land distribution across Latin America, including territories that later became the U.S. Southwest. Early ranchos, town grants, and agricultural holdings were often described using square varas. Because original surveys were conducted with ropes or rods rather than precise instruments, slight variations exist between historic definitions. Despite this, Spanish-era land patterns still rely on square vara conversions for legal clarification of old property descriptions. This unit provides essential insight into how colonial authorities organized land, particularly in regions with mixed indigenous and European land traditions.
