IMPORTANCE OF UNIT & IT’S COVERSTION
Unit are used to make all quantities in same manner.
SI or metric system based on principle that all
quantities of measured property have same unit.
It is used to convert larger unit or smaller unit.

WHAT IS CHAIN SURVEING ?
 Chain surveying is the type of surveying in which only linear
measurements are taken in the field.
 This type of surveying is done for surveys of small extent to
describe the boundaries of plot of land to locate the existing
features on them.
 It is the method of surveying in which the area is divided into
network of triangles
