>>>>Representative Fraction ( R. F. ): The third type of scale is R.

F. It shows the relationship between the map distance and the

corresponding ground distance in units of length. The use of units to

express the scale makes it the most versatile method.

R. F. is generally shown in fraction because it shows how much the

real world is reduced to fit on the map. For example, a fraction of 1 :

24,000 shows that one unit of length on the map represents 24,000 of

the same units on the ground i.e. one mm, one cm or one inch

on the map representing 24,000 mm, 24,000 cm and 24,000 inches,

respectively of the ground. It may, however, be noted that while converting

the fraction of units into Metric or English systems, units in centimetre or

inch are normally used by convention. This quality of expressing scale in

units in R. F. makes it a universally acceptable and usable method. Let us

take R. F. of 1 : 36,000 to elaborate the universal nature of R. F.

:50000 can be shown as 1/50000 as well. Here such a scale means that one unit of measurment on the map is equal to 50000 of the same unit on the ground. Such a unit can be anything such as centimetre, meter, feet, inches, your finger length, half a lenght of a pencil, etc.
