About Are
The are is 100 m². It is a metric land-area unit that sits between square meters and hectares.
About Acre

How to convert ares to acres
1 are is equal to 0.02471053814672 acre:
1 a = (100 m² ÷ 4046.8564224 m²) ac = 0.02471053814672 ac
Each are is defined as 100 m² and each acre as 4046.8564224 m², so one a equals 100 ÷ 4046.8564224 ac = 0.02471053814672 ac.
Let a(a) be the numeric value of the same area measured in Are (a), and a(ac) the value in Acre (ac). Then:
a(ac) = a(a) × (100 / 4046.8564224)
Equivalently, divide by how many a fit into one ac (m² per ac divided by m² per a):
a(ac) = a(a) ÷ 40.468564224
Or: acre = are ÷ 40.468564224
Examples
Example #1: Convert 20 a to acre
20 a = 20 a × (100/4046.8564224) ac = 0.4942107629 ac
20 a = 20 a ÷ 40.468564224 = 0.4942107629 ac
Example #2: Convert 50 a to acre
50 a = 50 a × (100/4046.8564224) ac = 1.2355269073 ac
50 a = 50 a ÷ 40.468564224 = 1.2355269073 ac
Summary
To convert Are to Acre, multiply the value in a by the ratio of square meters per a divided by square meters per ac. Equivalently: value_ac = value_a × (100 / 4046.8564224). Numerically, 1 a equals 0.024710538146716532 ac.
Relationship context
