What is a square foot?

The square foot, denoted as sq ft or ft², is an element of the size of area widely employed in the USA, Canada, and several other nations where a method of measures established on feet and inches survives. It is the area equal to the square of one foot in length and width. One just foot is analogous to around 0.0929 square m.

Historically, the square ft originated in ancient height methods, where various lengths were established on parts of the human body, such as feet. This was opportunely for calculating land locations and buildings in the pre-industrial era. Later, the criteria method was standardized and refined to evolve more accurately and consistently.

Today, ft² is widely utilized to calculate residential and commercial square footage, as well as in building and real estate. For illustration, when buying a property, you may be informed of the square footage of the house. This metric is also helpful for estimating the required square footage when planning furniture, renovations, or landscaping. Thus, the square feet remain a fundamental and usually operated metric that can facilitate counting and approximating the sizes of various things and spaces.

What is an acre?

An acre or ac for short is still one of the popular and common metrics in Great Britain and other English-speaking regions of the world. It is utilized in trade and can be used officially, as its correspondence to the standard options is established.

Only in the middle of the XX century, scientists determined acre as nearly 4046.856 square meters, 0.004 square kilometers, 0.405 ha, or 4840 square yards. Therefore, this option keeps its position on the land market and can be easily recalculated to other units, including those from the unified system.
