An acre (symbol: ac) is a unit of area commonly used in the Imperial and US customary measurement systems. One acre is equivalent to 43,560 square feet, or about 4,047 square meters.
The acre has its origins in the Middle Ages, where it was defined as the amount of land that could be plowed in one day by a yoke of oxen. The size of an acre varied over time and by region until it was standardized in the 19th century to 43,560 square feet.
Acres are commonly used in the United States, the United Kingdom, and other countries that use the Imperial system to measure large areas of land, such as farms, forests, and real estate properties. It is a standard unit of measurement in real estate transactions, agricultural land measurement, and land planning.
A square mile (symbol: sq mi or mi²) is a unit of area used in the Imperial and US customary measurement systems. One square mile is equivalent to 640 acres or about 2.59 square kilometers.
The square mile originated from the mile, a unit of length that has been used since Roman times. The use of the square mile as a unit of area became more standardized with the introduction of the Imperial system in the 19th century.
Square miles are commonly used in the United States, the United Kingdom, and other countries that use the Imperial system to measure large geographic areas, such as cities, counties, and entire countries. It is a standard unit of measurement in geography, land planning, and environmental studies.
To convert from acres to square miles, you can use the following formula:
Acres to square miles: ( \text{sq mi} = \frac{\text{ac}}{640} ) Convert Acres to Square Miles: Use the formula: ( \text{sq mi} = \frac{\text{ac}}{640} ) Calculation: ( \frac{320}{640} = 0.5 ) sq mi Example 1: If you have a plot of land that is 480 acres, convert it to square miles using the formula (480 acres (\div) 640 = 0.75 sq mi). Example 2: For a farm that is 1,200 acres, convert to square miles using the formula (1,200 acres (\div) 640 = 1.875 sq mi). Inches, centimeters, and feet are units of length used in different measurement systems. An inch (symbol: in) is a unit in the Imperial and US customary systems, a centimeter (symbol: cm) is part of the metric system, and a foot (symbol: ft) is also a unit in the Imperial and US customary systems. Inches to centimeters: ( \text{cm} = \text{inches} \times 2.54 ) Centimeters to feet: ( \text{feet} = \frac{\text{cm}}{30.48} ) Convert Inches to Centimeters: Use the formula: ( \text{cm} = \text{inches} \times 2.54 ) Calculation: ( 20 \times 2.54 = 50.8 ) cm Convert Centimeters to Feet: Use the formula: ( \text{feet} = \frac{50.8}{30.48} ) Calculation: ( \frac{50.8}{30.48} \approx 1.67 ) feet Example 1: If you have a length of 15 inches, first convert it to centimeters (15 inches (\times) 2.54 = 38.1 cm), then convert to feet (38.1 cm (\div) 30.48 ≈ 1.25 feet). Example 2: For a 35-inch measurement, convert to centimeters (35 inches (\times) 2.54 = 88.9 cm), then convert to feet (88.9 cm (\div) 30.48 ≈ 2.92 feet). By following these steps, you can easily convert any measurement from inches to centimeters to feet, ensuring accuracy and ease in your calculations.Quick Reference Conversion Table
