The Metric System

The metric system is a system of weight and measurement which was first adopted by France and is now almost universally used in the sciences and art. The greater part of population of the world works on the metric system.

Basic standards: Relation between English measure and Metric measure is as follows.

1 inch               = 25.4 mm                   = 2.54 cm

1 meter             = 39.37 inches             = 1.09 yards

1 liter                = 1.76 pints                  = 0.22 galls (imp)

1 gallon (imp)   = 4.546 liters

1 gallon (US)    = 3.785 liters

1 pound avp     = 0.4536 kilograms

1 kilogram        = 2.2046 pound avp

The metric system of unit called centimeter – gram – second (CGS) system is commonly used in scientific circle, and meter – kilogram – second (MKS) or metro – ton – second (MTS) system is more generally used in engineering.
