Formula
square yards = square miles × 3097600
This factor comes from each unit's defined relationship to the category's base unit: 1 square mile equals 2589988.11034 base units, and 1 square yard equals 0.83612736 base units, so dividing one by the other gives the direct square mile-to-square yard factor of 3097600.
Simple example
1 mi2 × 3097600 = 3,097,600 yd2
1 square mile = 3,097,600 square yards.
Real-world example
10 mi2 × 3097600 = 30,976,000 yd2
10 square miles = 30,976,000 square yards.
Conversion table
| Square mile (mi2) | Square yard (yd2) |
|---|---|
| 1 mi2 | 3,097,600 yd2 |
