The following readings were taken with a level on a 5m staff in a levelling operation from points 1 to 12, (2.08, 1.625, 3.2, (1.67 and 2.74) CP, 218, (0.825 and 1.12) CP, 2.95, (1.35 and 2.55) CP, 4.05, (1.75 and 3.35) CP, 2.78, 3.27). Points 1 and 12 are a bench marks having elevations (210 m and 212.55m respectively. 1- Find elevation of all points by rise and fall method and apply appropriate check. 2-Determine the loop closure and adjust the calculated value of the elevations.

Unit Conversion

Standard units are also called SI units. SI units are used for measuring a physical quantity satisfying certain conditions. There are two types of units: fundamental units and derived units. Fundamental units are physical quantities that are independent, that is, they do not depend on other quantities like mass, length, or time. There are plenty of quantities in our lives which need to be measured and compared. Measuring is the comparison of a particular physical quantity with its reference value. A unit is a measure of a fixed physical quantity. A physical quantity is the product of a unit and the numerical value we need to compare with.
