About Square Feet
Square feet (ft²) measure area; one ft² is a square with sides of 0.3048 m (international feet-based definitions). Real estate, interior design, and HVAC often use square feet.
About Are
The are is 100 m². It is a metric land-area unit that sits between square meters and hectares.
How to convert square feet to ares
1 square feet is equal to 0.0009290304 are:
1 ft2 = (0.09290304 m² ÷ 100 m²) a = 0.0009290304 a
Each square feet is defined as 0.09290304 m² and each are as 100 m², so one ft2 equals 0.09290304 ÷ 100 a = 0.0009290304 a.
Let a(ft2) be the numeric value of the same area measured in Square Feet (ft2), and a(a) the value in Are (a). Then:
a(a) = a(ft2) × (0.09290304 / 100)
Equivalently, divide by how many ft2 fit into one a (m² per a divided by m² per ft2):
a(a) = a(ft2) ÷ 1076.39104167097207
Or: are = square feet ÷ 1076.39104167097207
Examples
Example #1: Convert 20 ft2 to are
20 ft2 = 20 ft2 × (0.09290304/100) a = 0.018580608 a
20 ft2 = 20 ft2 ÷ 1076.39104167097207 = 0.018580608 a
Example #2: Convert 50 ft2 to are
50 ft2 = 50 ft2 × (0.09290304/100) a = 0.04645152 a
50 ft2 = 50 ft2 ÷ 1076.39104167097207 = 0.04645152 a
Summary
To convert Square Feet to Are, multiply the value in ft2 by the ratio of square meters per ft2 divided by square meters per a. Equivalently: value_a = value_ft2 × (0.09290304 / 100). Numerically, 1 ft2 equals 0.0009290304000000001 a.
