Measuring length using vernier callipers. Vernier callipers is used when higher accuracy in measurement is required and this cannot be done using a metre rule. Vernier callipers has two scales; main scale and vernier scale. Outside jaws are used to measure both lengths and external diameters, inside jaws for measuring internal diameters while the tail […]
MEASUREMENT IN PHYSICS Measurement of area and volume Concept & measurement of time and ways of measuring time. MEASUREMENT OF VOLUME Volume of liquid objects is measured using instruments such as cylinder, burette, pipette, eureka can, etc. For regular solid objects, their volume could be determined using their mathematical formula.

MEASUREMENT.
In order to measure we need to know or define the quantity to be measured and the units for measuring it.
In 1971 a system known as the International System of Units (Systeme’ Internationale) and seven basic units were agreed upon as follows. Other quantities can be obtained from these basic quantities and are referred to as derived quantities.
