The history behind square feet and acres
The history of square feet and acres traces back to ancient measurement systems. The square foot, a unit of area, evolved from the standard size of a square whose sides are one foot long. This measurement was widely adopted in Europe and later in the United States for property and construction purposes. The acre, originally based on the amount of land a yoke of oxen could plow in a day, has its roots in medieval England. It was defined as the area of a rectangular plot of land 1 furlong (660 feet) long and 1 chain (66 feet) wide, equaling 43,560 square feet.
Steps to convert square feet to acre
The best way is to use the established formula for 1 square feet to acre conversion. The formula is given as follows:
1 Acre equals 43560 sq ft.
1 sq ft equals 0.00002295684 acre
Acre equals sq.ft.* 2.29568E-5.
This will help find the final outcome without any hassle. Let us learn more about it with the help of a few instances:
Instance 1: Find the conversion for 10000 sq.ft. in acres
10000 sq.ft. = 10000* 0.0000229568 = 0.229568 acres.
Instance 2: Find the conversion for 15000 square feet in acres
15000 sq.ft. = 15000*0.0000229568 = 0.344353 acres.
Pro Tip: If you are unable to picture what a square foot looks like, try drawing a square that’s 1 foot tall by 1 foot wide—you have got a square foot! Many such squares stacked up against one another equals a whole floor, wall, or sheet of fabric, etc. This way, you are measuring how much an area is covering instead of how wide or how tall it is.
