Comparison of 1 square foot with some Imperial and metric units of area. The square foot (pl. square feet; abbreviated sq ft, sf, or ft 2; also denoted by ' 2 and ⏍) is an imperial unit and U.S. customary unit (non-SI, non-metric) of area, used mainly in the United States, Canada, the United Kingdom, Bangladesh, India, Nepal, Pakistan, Ghana, Liberia, Malaysia, Myanmar, Singapore and Hong Kong.
The precise conversion is 1 cuerda = 3,930.395625 m 2. [2] The term "Spanish acre" instead has been used sometimes by mainlanders. [1] A cuerda and an acre have often been treated as equal because they are nearly the same size. According to Carlos Menocal Villagran, [3] in Guatemala, the term cuerda refers to a unit of area and can have various ...
Conversion of units is the conversion of the unit of measurement in which a quantity is expressed, typically through a multiplicative conversion factor that changes the unit without changing the quantity. This is also often loosely taken to include replacement of a quantity with a corresponding quantity that describes the same physical property.
Among the Guatemalan units of measurement some are based on old Spanish units; they include the vara and cuadra linear measurements; the vara cuadrada, the manzana and the cuerda units of area; and the libra, arroba, quintal and garrafón units of weight and volume.
As the name suggests, an acre-foot is defined as the volume of one acre of surface area to a depth of one foot.. Since an acre is defined as a chain by a furlong (i.e. 66 ft × 660 ft or 20.12 m × 201.17 m), an acre-foot is 43,560 cubic feet (1,233.5 m 3).
1 toise was divided in 6 feet (French: pieds) or 72 inches (pouces) or 864 lines (lignes) in France until 1812.; In 1799 the metre was defined to be exactly 443.296 lignes or 13,853 ⁄ 27,000 toise, with the intention that the metre should equal 1 ⁄ 10,000,000 of the distance from the pole to the equator.
This gives the exact conversion factor: One pound-foot = 1.355 817 948 331 400 4 newton metres . The name "pound-foot", intended to minimize confusion with the foot-pound as a unit of work , was apparently first proposed by British physicist Arthur Mason Worthington .
(mol/s)/(m 2 ·mol/m 3) = m/s; Note, the units will vary based upon which units the driving force is expressed in. The driving force shown here as ' ' is expressed in units of moles per unit of volume, but in some cases the driving force is represented by other measures of concentration with different units.
