Scale (ratio) — The concept of scale is applicable if a system is represented proportionally by another system. For example, for a scale model of an object, the ratio of corresponding lengths is a dimensionless scale, e.g. 1:25; this scale is larger than 1:50.In … Wikipedia
Dimensionless quantity — In dimensional analysis, a dimensionless quantity or quantity of dimension one is a quantity without an associated physical dimension. It is thus a pure number, and as such always has a dimension of 1.[1] Dimensionless quantities are widely used… … Wikipedia

Scale invariance — In physics and mathematics, scale invariance is a feature of objects or laws that do not change if length scales (or energy scales) are multiplied by a common factor. The technical term for this transformation is a dilatation (also known as… … Wikipedia
Dimensionless physical constant — In physics, a dimensionless physical constant (sometimes fundamental physical constant) is a universal physical constant that is dimensionless having no unit attached, so its numerical value is the same under all possible systems of units. The… … Wikipedia
Scale factor (cosmology) — The scale factor or cosmic scale factor parameter of the Friedmann equations is a function of time which represents the relative expansion of the universe. It is sometimes called the Robertson Walker scale factor.[1] It is the (time dependent)… … Wikipedia
Scale factor (Universe) — The scale factor, parameter of Friedmann Lemaître Robertson Walker model, is a function of time which represents the relative expansion of the universe. It relates physical coordinates (also called proper coordinates) to comoving coordinates.: L … Wikipedia

Rockwell scale — The Rockwell scale is a hardness scale based on the indentation hardness of a material. The Rockwell test determines the hardness by measuring the depth of penetration of an indenter under a large load compared to the penetration made by a… … Wikipedia
Logarithmic scale — A logarithmic scale is a scale of measurement that uses the logarithm of a physical quantity instead of the quantity itself. Presentation of data on a logarithmic scale can be helpful when the data covers a large range of values ndash; the… … Wikipedia
