How many feet is 138cm




















It may also be occasionally written as a square with a slash through it. Its abbreviation is commonly written as sqft or sq ft. As a unit of area, it has a magnitude equivalent to the area of a square with sides of 1 foot. You will see soon how to convert from square meters to square feet, from square inches to square feet, etc But for now, let's talk about some situations in which you might want to calculate the square footage of something using a simple square footage formula.

These situations include selling, leasing, renting, or buying a house or a room; building a shed or a garage for your car; or maybe even when painting a room. In all these situations, our square footage calculator will help you. Although, for the last three, we recommend looking at our paint calculator. Let's now see how to calculate square footage when you already know the area in different units.

This is the most simple use of the square footage calculator. To use this conversion feature, you could use the area conversion tool on this website or simply follow the following steps:. For example, we might want to know how big a m 2 sqm expressed in sq ft.

In other words, we would want to convert from sq m to sq ft and find out the square footage of that house, which is:. The procedure of converting square inches to square feet or from acres to sq ft is the same as converting from square meters to square feet.

In the following examples, you will find the most common of these conversions: how many square feet are in an acre. Intuitively, this process can also be done in reverse. Therefore, we can not only find square footage when we know its value expressed in the other units but also find an area in any units from a given square footage. Before we get into the nitty-gritty of how the calculator works and what is the square footage formula, it's useful to know how to use the calculator , and what each of the components mean.

To use the calculator is as simple as setting the known values and letting the system calculate the rest. This means that you can use this calculator to compute the price per square foot of a property if you know the total price and total square footage. For complex room layouts, divide up the room into simple shapes, such as rectangles, squares, etc. If you've entered a unit price, you'll also get the total cost.

Technically, it is not correct to talk about the square footage formula ; we should rather talk about area formula. However, as long as we understand that a square footage formula is just another way to say that we will take an area formula and apply it using square feet , I think we can all agree the precise technical term doesn't matter much here. The square footage formula is different depending on the shape of the object we want to calculate the area for.

The simplest and most common case is the square, or, more generally, the rectangle. For these polygons, the formula is as simple as taking the length of two adjacent sides in feet and multiplying them together. Since we are working with a rectangle, we know that taking two next sides is the same as taking the height and the width of it. If we name these two sides A and B, the other two necessarily must have the same dimensions as A and B, respectively.

This might sound like a simple mathematical formula , but it is precisely how to measure the square footage of a rectangular room in real life. We just need to measure two consecutive sides in feet and multiply the values together.

This square footage formula is, in fact, the same as the one used in the area of a rectangle calculator , but, in case of this calculator, used to find square footage instead of calculating polygons. Not all rooms are perfect squares or rectangles, and it becomes more tricky to calculate square footage in such a situation. If the room is almost rectangular, one can get a pretty good approximation just by considering it as a rectangular and performing a similar calculation as we have seen before.

The history of measurement scales has been quite varied and extensive. In the past, many different distance units were used to measure the length of an object. In the absence of any standard unit for measurement, people utilized body parts such hand, foot and cubit for the purpose of measuring any height of any object or humans.

These units were not uniform and varied in length from one era to another.
