What is a Square Foot?
The square foot is the area of a square one foot on a side, and it is the unit American and Indian real estate runs on — apartments, offices and warehouses are advertised, valued and rented by it, while most of Europe quotes the identical thing in square meters. It is also where the commonest conceptual mistake about area surfaces. Area scales with the square of length, so converting a room’s dimensions and converting its floor area are not the same operation: double a room’s length and width and you have not doubled the floor, you have quadrupled it.
What is an Acre?
The acre is the awkward number in the system, and the reason is that it was never a piece of geometry: it was the area a man with a single ox could plough in a day. That gave it a shape as well as a size — one furlong long by one chain wide, the furlong being the length of the furrow before the team was turned around. Formalised as 4,840 square yards, it never rounded off to anything tidy, and nobody minded, because it described a day’s work. It is still the standard unit for land in the US and for farmland and property in the UK and India.
To put both in perspective: a typical US one-bedroom apartment is around 700 square feet, while a football pitch is a bit over an acre.
