64. METRIC SYSTEM - also known as the International System of Units - a rational and comprehensive system of measurement that simplifies the complexities of measuring various physical quantities.  - most widely used system of measurement worldwide, utilized not only in science but also in everyday contexts. 

65. METRIC SYSTEM - the basic unit of length, capacity and weight are meter , liter and gram respectively. - units longer and shorter than the meter, liter or gram are achieved by adding prefixes to the base unit.
