Metric system of Measurement

The metric system of measurement is used in science, engineering, and commerce based on the International System of Units (SI). It is the most widely used system of measurement in the world. The metric system consists of seven base units: the meter (m), kilogram (kg), second (s), ampere (A), kelvin (K), mole (mol), and candela (cd). These base units are then used to derive other units such as Newton (N), Pascal (Pa), joule (J), and watt (W).

Name of Unit	Symbol	Definition
Meter	m	The length of the path travelled by light in a vacuum in 1/299,792,458 of a second
Kilogram	kg	The mass of a particular international prototype kept at the International Bureau of Weights and Measures
Second	s	The duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom
Ampere	A	The constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross-section, and placed 1 meter apart in vacuum, would produce between these conductors a force equal to 2 x 10-7 newtons per meter of length
Kelvin	| K	The fraction 1/273.16 of the thermodynamic temperature of the triple point of water
Mole	mol	The amount of substance of a system which contains as many elementary entities as there are atoms in 0.012 kilogram of carbon-12
Candela	cd	The luminous intensity, in a given direction, of a source that emits monochromatic radiation

Measurement of length 1 cm = 10 mm 1 mm = 0.1 cm 1 m = 100 cm 1 cm = 0.01 m 1 km = 1000 m 1 m = 0.001 km

Measurement of mass / weight

1 cg = 10 mg

1 mg = 0.1 cg

1 g = 100 cg

1 cg = 0.01 g

1 g = 1000 mg

1 mg = 0.001 g

1 kg = 1000 g

1 g = 0.001 kg

1 tonne = 1000 kg

1 kg = 0.001 tonne

Measurement of volume

1 cl = 10 ml

1 ml = 0.1 cl

1 l = 100 cl

1 cl = 0.01 l

1 l = 1000 ml

1 ml = 0.001 l

1 kl = 1000 l

1 l = 0.001 kl
