In 1 square meter there are 1 centiares. Meanwhile in 1 centiares there are 1 square meter. Keep reading to learn more about each unit of measure and how they are calculated. Or just use the Centiares to Square meter calculator above to convert any number.

To convert square meters (m²) to centiares (cent), use a simple land area conversion.
cent = m² ÷ 40.468564224
For most land measurements, rounding to 2 to 4 decimal places is enough.
A square meter (m²) is a metric unit of area. It equals the area of a square that is 1 meter long and 1 meter wide. It’s used for rooms, homes, buildings, and land in many countries.
A centiare (ca) is a metric unit of land area. It equals 1 square meter. It comes from the are system, where 100 centiares make 1 are.
There is 1 centiare in 1 square meter.
1 m² = 1 ca
There is 1 square meter in 1 centiare.
1 ca = 1 m²
The conversion is a one-to-one match.
Centiares = Square meters
ca = m²
Use the same number and keep the value unchanged.
Example: 45 m² = 45 ca
Example: 120.5 m² = 120.5 ca
Use the same number and keep the value unchanged.
Example: 30 ca = 30 m²
Example: 2.75 ca = 2.75 m²
They match because a centiare is defined as exactly 1 square meter. The centiare is part of the are-based system, but it uses the same metric area size.
Centiares show up most often in land and property notes, maps, and older records. Some places prefer centiares for small land areas because they relate to ares and hectares.
Centiares fit into a simple set of metric land units:
Yes. Since 1 m² equals 1 ca, the conversion is exact with no rounding needed. You only round if you choose fewer decimal places for display.
Yes. Decimal values work the same way because the units are equal.
Example: 0.25 m² = 0.25 ca
Example: 99.99 m² = 99.99 ca
The square meter is an SI unit. The centiare is not an SI unit, but it’s a metric unit used with the are system. It stays easy to use because it equals 1 m².
