METRIC UNITS OF MEASUREMENT

      The metric system was first proposed in 1791. The French Revolutionary Assembly adopted it in 1795, and the first metric standards (a standard meter bar and kilogram bar) were adopted in 1799.

7. Units of Length

Name	Symbol	Value
millimeter	mm	1 mm = 0.001 m
centimeter	cm	1 cm = 10 mm
decimeter	dm	1 dm = 10 cm
meter	m	1 m = 10 dm = 1000 mm
dekameter	dam	1 dam = 10 m
hectometer	hm	1 hm = 10 dam
kilometer	km	1 km = 10 hm = 1000 m

8. Units of Area

Name	Symbol	Value
sq. millimeter	mm^2	1 mm^2 = 0.000001 m^2
sq. centimeter	cm^2	1 cm^2 = 100 mm^2
sq. decimeter	dm^2	1 dm^2 = 100 cm^2
sq. meter	m^2	1 m^2 = 100 dm^2
sq. decameter	dam^2	1 dam^2 = 100 m^2
sq. hectometer	hm^2	1 hm^2 = 100 dam^2
sq. kilometer	km^2	1 km^2 = 100 hm^2

9. Units of Liquid Value

Name	Symbol	Value
milliliter	mL	1 mL = 0.001 L
centiliter	cL	1 cL = 10 mL
deciliter	dL	1 dL = 10 cL
liter	L	1 L = 10 dL = 1000 mL
dekaliter	daL	1 daL = 10 L
hectoliter	hL	1 hL = 10 daL
kiloliter	kL	1 kL = 10 hL = 1000 L

10. Units of Volume

Name	Symbol	Value
cu. millimeter	mm^3	1 mm^3 = 10 ^−9 m^3
cu. centimeter	cm^3	1 cm^3 = 1000 mm^3
cu. decimeter	dm^3	1 dm^3 = 1000 cm^3
cu. meter	m^3	1 m^3 = 1000 dm^3

11. Units of Mass

Name	Symbol	Value
milligram	mg	1 mg = 0.001 g
centigram	cg	1 cg = 10 mg
decigram	dg	1 dg = 10 cg
gram	g	1 g = 10 dg
dekagram	dag	1 dag = 10 g
hectogram	hg	1 hg = 10 dag
kilogram	kg	1 kg = 10 hg = 1000 g
megagram	Mg	1 Mg = 1000 kg = 1 t

U.S. UNITS OF MEASUREMENT

      Most of the U.S. system of measurements is the same as that forthe U.K. The biggest differences to be noted are
