Examples
1
Consider that a wildlife sanctuary covers 30 square miles. Convert this area from square miles to Acres.
Answer:
Given:
The area in square miles is:
Area(Square Miles) = 30
Formula:
The formula to convert area from square miles to acres is:
Area(Acres) = Area(Square Miles) × 640
Substitution:
Substitute given weight Area(Square Miles) = 30 in the above formula.
Area(Acres) = 30 × 640
Area(Acres) = 19200
Final Answer:
Therefore, 30 mi2 is equal to 19200 ac.
The area is 19200 ac, in acres.
2
Consider that a desert region spans 100 square miles. Convert this area from square miles to Acres.
Answer:
Given:
The area in square miles is:
Area(Square Miles) = 100
Formula:
The formula to convert area from square miles to acres is:
Area(Acres) = Area(Square Miles) × 640
Substitution:
Substitute given weight Area(Square Miles) = 100 in the above formula.
Area(Acres) = 100 × 640
Area(Acres) = 64000
Final Answer:
Therefore, 100 mi2 is equal to 64000 ac.
The area is 64000 ac, in acres.

Square Miles
A square mile (mi2) is a unit of area measurement equal to the area of a square with sides one mile in length, or 640 acres. It is commonly used to measure large land areas, such as cities, counties, or natural landscapes. Square miles are important in geography, urban planning, and environmental studies, helping to quantify and compare the vast extents of regions, national parks, and entire states or countries.
Acres
An acre is a unit of area measurement used primarily in the United States and the United Kingdom. It is equal to 43,560 square feet or about 4,047 square meters. Acres are commonly used in real estate, agriculture, and land management to describe the size of parcels of land. They provide a convenient way to discuss and compare land sizes, particularly in rural and agricultural contexts.
