What is an Acre

The acre is a unit of area with the symbol ac. An acre is a measure of land area in the British system of imperial units and United States customary units.

An acre is defined as an area of 66 ft x 660 ft, which equals 43,560 square feet. An area of acreage can be any shape -- it does not have to be a square or a rectangle.

Converting acres to square feet is a simple multiplication problem. Since 1 acre = 43,560 ft², multiply your number of acres to get the total in square feet. So sq ft = acres × 43,560.

What is a Square Foot

A square foot is a unit of area with the symbol ft² but you will also see people use sf, sqft and sq ft which all mean "square feet." For example, 3 square feet can be expressed as 3 ft², 3 sf, 3 sqft, or 3 sq ft.

One square foot is the area of a square where each side is 1 foot long. The area of this square is 1 ft x 1 ft = 1 ft² since area of a square or rectangle is calculated by multiplying length by width.

The foot is a unit of length in the British system of imperial units and United States customary units. One square foot is equal to 1/43,560 acres.
