                                     Measurements




                 Our environment has various things. Those things differ in
                 terms of volume, length and mass. In this chapter, you will
                 learn how to measure length, mass and volume of different
                 objects. You will also learn how to use those measurements.




                 Types of measurements

                 Measurement is the size, length or amount of something,
                 which is represented by numbers and units. There are two
                 types of measurements, namely standard measurements and
                 non-standard measurements.




                 Standard measurements

                 These are the approved measurements which are similar wherever
                 they are used.
