The land chain is 1 decametre in length, and is divided into 50 links, each 2 decimetres in 
length. Sometimes the double decametre is used, which nearly equals the English land chain. 
Long distances are expressed in kilometres.

100 sq. ceatimetres =1 sq. decimetre 
100 sq. detimetres =] sq. metre. 
100 sq. metres

100 sq. decametres =1 sq. hectometre 
100 sq. hectometres=1 sq. kilometre 
But 100 sq. metres=1 are (the unit for area), so the following table is used :—
