Square Yards to Square Feet (yd² to ft²)
1 square yard equals 9 square feet exactly.
How to convert square yards to square feet
To convert square yards to square feet, multiply the number of square yards by 9. This factor is exact. To go the other way, multiply square feet by 0.1111111111 (rounded).
square feet = square yards × 9
Example: 10 square yards = 90 square feet.
About these units
Square Yard (yd²)
9 square feet (0.8361 m²). Used for carpet, turf and land in the UK and India (where it is called a gaj).
Branches and rods lie behind this unit. The word yard comes from Old English gerd or gyrd, meaning a staff or measuring rod, and it first appears in the late seventh-century laws of Ine of Wessex, where a yard of land was a tax unit. Where its length came from is uncertain: pacing, the cubit and the arm of King Henry I have all been suggested. A square yard is simply a square of that length on each side.
After the 1959 agreement among six countries fixed the yard at exactly 0.9144 meter, the square yard became exactly 9 square feet, 1,296 square inches or about 0.836 m². It is used across the English-speaking world, notably in the United States, United Kingdom, Canada, India and Pakistan. In northern India it is called a gaj, and in Pakistan a gaz, and house plots there are often quoted in it. In the US and UK the yard, divided into eighths, is also how cloth is bought, so the square yard suits flooring and fabric in the same breath.
1 square yard = 0.83612736 square meters (exactly).

Square Foot (ft²)
Exactly 0.09290304 m². The standard unit for floor areas and real estate in the US, UK and India.
Feet came first, and they were not all the same length. As a body-based unit, the foot ranged historically between about 250 and 335 millimeters, with ancient Greek and Roman feet near 300 mm. In medieval England a statute foot was set at 10/11 of an older Belgic foot, and Charlemagne's attempt around 790 to standardize units largely failed. The square foot is simply that length squared, so its size changed along with the foot.
The 1959 international agreement fixed the foot at exactly 0.3048 meter, so one square foot is exactly 0.09290304 m², or 144 square inches. The United Kingdom adopted the new foot in 1964. Today the square foot is the usual way of listing property in the United States, Canada, the United Kingdom, India, Pakistan, Singapore and Hong Kong, although the measuring convention varies: agents may measure corner to corner, subtract unheated space, or add heated space that extends beyond the end-to-end measurement. The world's smallest park has been reported at 2.6 sq ft.
1 square foot = 0.09290304 square meters (exactly).
