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 Square Yard
The square yard is 9 square feet (3 ft × 3 ft). It appears in some sports fields, fabric, and older imperial measurements.
How to convert square feet to square yards
1 square feet is equal to 0.11111111111111 square yard:
1 ft2 = (0.09290304 m² ÷ 0.83612736 m²) yd2 = 0.11111111111111 yd2
Each square feet is defined as 0.09290304 m² and each square yard as 0.83612736 m², so one ft2 equals 0.09290304 ÷ 0.83612736 yd2 = 0.11111111111111 yd2.
Let a(ft2) be the numeric value of the same area measured in Square Feet (ft2), and a(yd2) the value in Square Yard (yd2). Then:
a(yd2) = a(ft2) × (0.09290304 / 0.83612736)
Equivalently, divide by how many ft2 fit into one yd2 (m² per yd2 divided by m² per ft2):
a(yd2) = a(ft2) ÷ 9
Or: square yard = square feet ÷ 9
Examples
Example #1: Convert 20 ft2 to square yard
20 ft2 = 20 ft2 × (0.09290304/0.83612736) yd2 = 2.2222222222 yd2
20 ft2 = 20 ft2 ÷ 9 = 2.2222222222 yd2
Example #2: Convert 50 ft2 to square yard
50 ft2 = 50 ft2 × (0.09290304/0.83612736) yd2 = 5.5555555556 yd2
50 ft2 = 50 ft2 ÷ 9 = 5.5555555556 yd2
Summary
To convert Square Feet to Square Yard, multiply the value in ft2 by the ratio of square meters per ft2 divided by square meters per yd2. Equivalently: value_yd2 = value_ft2 × (0.09290304 / 0.83612736). Numerically, 1 ft2 equals 0.11111111111111112 yd2.
Relationship context
Both units belong to US customary / imperial area measures. Relationships such as 9 ft² per yd² and 43,560 ft² per acre are exact under standard definitions. This tool uses SI-based square-meter factors for consistency.
