The Metric System
In the Metric system Metre is the unit measure of length, Are for surfaces, the Spere for solids, the Litre for capacity, the Gramme for weight.

Linear Measure

10 millimeters (mms) = 1 centimetre (cm) 10 cms = 1 decimetre (dm) 10 dms = 1 metre (m) 10 ms = 1 decametre (Dm) 10 Dms = 1 hectometre (Hm) 10 Hms = 1 kilometre (km) 10 kms = 1 Myriametre (Mm)

Surface or Square Measure

1 are = 100 square (sqs) metres 1 decare = 10 ares 1 hectare = 100 ares 1 deci-are = 1/10 of an Are 1 centi-are = 100 of an Are

Measure of Capacity

1 litre = 1000 cubic centimeters (c.c) 1 decalitre = 10 litres 1 hectolitre = 100 litres 1 kilolitre = 1000 litres 1 decilitre = 1/10 of a litre 1 centilitre = 1/100 of a litre 1 mililitre = 1000 litres

Measure of weight

10 milligrammes = 1 centigramme 10 centigrammes = 1 decigramme 10 decigrammes = 1 gramme 10 grammes = 1 decagramme 10 decagrammes = 1 hectogramme 10 hectogrammes = 1 kilogramme
