A square foot (ft2) is a unit of area used in the imperial system of measurement, which is common in the United States. Its plural form is square feet.
It's a fundamental measurement for understanding the size of any physical space.
A square foot is simply the area of a square with sides that are one foot long.
Since a foot equals 12 inches, that same space measures 12 by 12 inches, or 144 square inches in total.
For a quick comparison, a standard sheet of printer paper is smaller than one square foot. It's this straightforward measurement that makes it the standard for measuring rooms, houses, and floor plans.
In the United States real estate market, the square foot is the most common unit used to describe the size of a property.
This measurement, known as "square footage," represents the total floor area of apartments, houses, and commercial buildings.
Square footage is a primary factor in determining a property's value, rental price, and marketability.
Buyers and renters rely on this number to compare different properties and understand precisely how much living or working space they are getting. For example, knowing a bedroom is 120 square feet helps you visualize if your queen-sized bed will fit comfortably.
Since many parts of the world use the metric system, knowing how to convert square feet to square meters is essential.
The conversion is:
This conversion is crucial for international business, science, and real estate, as it enables a clear understanding of the area, regardless of the measurement system used.
Calculating the square footage of a rectangular or square area is simple. You need to multiply the length of the space by its width.
Formula: Length × Width = Square Footage
For example, if a room is 10 feet long and 12 feet wide, its square footage is 120 ft2 (10 ft × 12 ft = 120 ft2).
An acre (ac) is a common unit of area used to measure land in the United States and the United Kingdom.
It is equal to exactly 43,560 square feet.
Because it can be hard to picture that size, this guide breaks down the acre's origins, dimensions, and how it compares to other units.
The acre has deep roots in agriculture. Historically, it was defined as the amount of land that one person with a single ox could plow in one day.
This practical, work-based unit was measured as an area one "furlong" long (660 feet) by one "chain" wide (66 feet).
This origin explains why the acre became a standard for land measurement long before modern units were adopted.
Many people ask about the dimensions of an acre, but because it's a measure of area, it has no required shape or specific length.
While it equals 43,560 square feet, it doesn't have to be a perfect square. An acre can be a long rectangle, an L-shape, or even a circle—as long as the total area adds up.
To help you visualize an acre, imagine a standard American football field, including the end zones. One football field is about 1.32 acres, which means a single acre would cover about three-quarters of it.
While the acre is standard in the US, most of the world uses the hectare, a metric unit of land measurement.
This difference is crucial for anyone working in international real estate, agriculture, or science.
