Physical quantities such as length‚ weight‚ time‚ speed‚ force‚ and mass are measured with standard units. Therefore the magnitude if a physical quantity is given by a number and standard unit of measurement. Examples: 5 meters‚ 60 kilograms. SI units are the international system of units (system international). The SI Base Units for the seven
