The most common use of area measurement units are in real estate and architecture where space is naturally translated into money.

The accurate area calculation can make the differance between a stable and straight building and a completely skewed one or unstable one.

In real estate , area is translated directly to money and because of globalization and the fact that foreign investors buy land and property in almost any country, converting the area units from local ones to the investors common ones is cruicial and imperative altogether.
