      Section 4: Measurement and Safety. The “International System of Units” (SI—short for “system international”) is the standard measurement system used by scientists around the world. Quantities of measurement: length, volume, mass and temperature. Derived quantities: You combine other measurements. For example: area and density.

      All measurable quantities are called physical quantities such as length, mass, time and temperature. Physical quantities usually contain two characteristics. One is numerical magnitude and other is unit in which it measured. For example length of a student is 100cm so 100 is a numerical magnitude and cm is unit in which it measured.
