a number used as a multiplier in scaling
The factor by which the number of scale divisions indicated or recorded by an instrument must be multiplied to compute the value of a measured variable.
of a map: ratio of distance on the ground to distance on the map. The denominator of the conventional representation of map scale.
The factor by which the output signal of an instrument (volts, milliamps, frequency, etc.) should be multiplied to compute the value of the measured variable.
The scale factor determines the size of MicroMODEL plots. For scaled plots this is the map scale at which the plot is desired. For unscaled plots the scale factor is generally 1.0 for a standard report size plot.
a constant multiplier which converts an instrument reading to a measured value in standard units for the parameter being measured
Field located in the performance indicator edit window. Scale factor allows large values with many trailing zeros to be truncated during measurement entry to reduce user errors and increase speed of data entry. For example, waste to landfill may be expressed in millions of kilogrammes but rounded to the nearest 1000 Kg. In this case, a scale factor of x3 could be used and instead of a user entering in a value like "1345000" they could enter in "1345".
The ratio of a distance measured on a scale drawing to the corresponding distance measured on the actual object.
(Also called map scale, map factor.) The ratio between the distance separating two points on a map of the earth's surface at a standard latitude (or latitudes) and the distance between the corresponding points on the earth's surface itself. For most map projections, this factor is a slowly varying function of latitude, and for synoptic- chart base maps it is usually of the order of 10−6 to 10−7. The scale factor is sometimes defined as the reciprocal of the above ratio. Compare conformal map.
A scale factor is a number which scales, or multiplies, some quantity. In the equation y=Cx, C is the scale factor for x. C is also the coefficient of x, and may be called the constant of proportionality of y to x.
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.
A scale factor is used in computer science when a real world set of numbers needs to represented on a different scale in order to fit a specific number format. For instance, a 16 bit unsigned integer (uint16) can only hold a value as large as 65,53510. If unint16's are to be used to represent values from 0 to 131,07010, then a scale factor of 1/2 would be introduced.
