1. The square meter.
The square meter is the area of a square whose sides measure exactly one meter. Its symbol is: m.^{2}.
2. Multiples of the square meter.
These are:
1 square decameter is equal to 100 square meters: 1 dam^{2} = 100 m^{2} .
1 square hectometer is equal to 100 00 square meters: 1 hm^{2} =
100 00 m^{2}.
1 square kilometer is equal to 100 00 00 square meters: 1 km^{2} =
100 00 00
m^{2}.
1 square myriameter is equal to 100 00 00 00 square meters: 1
mam^{2} = 100 00 00 00 m^{2}.
To measure fields, we use agricultural units. These are:
1 hectare is equal to hm^{2}: ha = hm^{2} = 100
00 m^{2}.
1 area is equal to dam^{2}: a = dam^{2} = 100 m^{2}.
1 centiare is equal to m^{2}: ca = m^{2} = 1 m^{2}.
The units of surface increase and decrease from 100 to 100.
The superior unit is 100 more than the lower.
