What these units are
Square miles (mi²). A square mile is about 2.59 square kilometers, or exactly 640 acres. It is used for land and territory areas in the United States and the UK, and for large ranch or park sizes.
Square yards (yd²). A square yard is 0.83612736 square meters, or 9 square feet. It is used for carpet, landscaping and fabric in imperial-measure countries.
Every factor is an exact definition, so the only loss is display rounding. Land figures quoted in acres and hectares are usually rounded at the source.
Converting Square miles to Square yards in practice
Working in square miles
A square mile is the area of a square one mile on each side, exactly 2.589988110336 square kilometers, or exactly 640 acres. It is built from the statute mile and never from the nautical mile.
Metropolitan areas, counties, states, large ranches and national parks are measured in square miles in those countries. Weather maps and watershed studies also report extents in square miles.
The relation to acres is exact, with 640 acres in one square mile, and the relation to square kilometers follows from the exact definition of the mile. Rounded display can perturb the last digit of a two-way conversion.
Treating square miles as if they were mile figures is the usual slip: an area scales with the square of the length, so a square mile is not 1.609 square kilometers. Land is often better compared in acres or hectares.
Square miles, acres and square kilometers all describe large areas, and the relations are exact: 640 acres to a square mile, 2.59 square kilometers to the same measure. A county in one unit and a park in another do not compare until both are converted.
Checking a square miles to square yards conversion
Area factors are the square of the corresponding length factors, so the numbers move much faster than a reader expects. A square meter contains 10,000 square centimeters, and a square kilometer a million square meters, not a thousand.
The units that share a name across systems are still different sizes: a square mile and a square kilometer differ by a factor of about 2.59, and an acre is a fixed area rather than a square with equal sides, so it does not convert like the length units it is named after.
Land is where the reciprocal matters most, because acres and hectares are both in use for the same plots. When a figure moves between them, check it against a shape you can picture — a hectare is a square 100 meters on each side — rather than against the number alone.
