Scale represents the ratio between map distance and ground distance. Representative Fraction, Graphical scale, Linear scale and Comparative scale, Statement scale all are various categories of scale.
In Representative Fraction (R.F) values are represented in ratio format. Here, 1 cm map distance representing 1,00,000 cm ground distance. As 1 km= 1,00,000 cm. That's why 1 cm to 1 km means 1 cm map distance represents 1 km ground distance in reality.
Statement scale represents the values in a sentence. For eg. 1 cm to 1 km. Linear scale represents the values in primary and secondary divisions likewise Comparative scale compares two different units in a single scale.
