Now we are going to show you a few examples how to convert inches to feet step by step.

How to convert inches to feet

Have a look at these examples:

Let’s start with 2 inches. Divide 2 by 12. It gives 2/12, after reduce the fraction it is equal 1/6 ft. Do you need a decimal? The result is equal 0.16666666667 ft. Now round it off to two decimal places. The final result is equal 0.17 ft.

Now try to convert 5 inches into feet. Divide 5 by 12. It gives 5/12. In this case you can’t reduce the fraction but you can write the result as a decimal. It is equal 0.41666666667 ft. After rounding off to two decimal places, the final result is equal 0.42 ft.

How many feet are in 8 inches? And again, divide 8 by 12. It gives 8/12. Now reduce the fraction. It gives 2/3. As a decimal it is equal 0.66666666667 ft. Round off the result to two decimal places. The final result is equal 0.67 ft.

Let’s calculate something bigger. How many feet in 30 inches? Divide 30 by 12. It gives 30/12. After reducing the fraction it is equal 5/2 and that’s 2 ½ ft. As a decimal it is equal 2.5 ft.

The last example. Convert 45 inches into feet. 45/12 = 15/4 = 3 ¾ ft. The final result, as a decimal, is equal 3.75 ft.

As you can see, it is not complicated. We are sure that all of you can calculate inches into feet after reading this part of article.

Besides inches and feet there are also square inches and square feet. Before we show you how to calculate square inches to square feet, we want to give you some basic information about these units.

Both of them are units of area. Square inch is area of a square which sides are equal one inch. Square inch can be written, for instance, as:

  • Square in,
  • Sq inch or sq in,
  • Inch2 or in2.

Square inch, same as inch, is used mostly in United Kingdom and the United States.

In turn, square foot is area of a square which sides are equal one foot. You can write it as:

  • Sq. ft,
  • Sf,
  • Ft2.

It is a unit in Imperial and United States customary unit of area. It is used mostly in United Kingdom and the United States but also sometimes in, for instance, Hong Kong, Canada, Ghana or Pakistan. This unit is commonly used to measure area of real estate, such as apartments or houses.

You need to know how many square feet are in one square inch before we start calculations.

  • 1 square foot = 144 square inches,
  • 1 square inch = 1/144 square foot or 0.00694 in abbreviated form.

So what is a formula to calculate square inches into square feet? It is down below:

Number of square inches / 144 = the result in square feet

Let’s try this formula.

How many square feet are in 5 square inches? Divide 5 by 144. You can write it as a fraction – 5/144 or as a decimal - 0.03472 square feet (in short form).

Try to convert 50 square inches into square feet. Divide 50 by 144. It gives 50/144. Now reduce the fraction. It is 25/72. The final result as a decimal is equal 0.3472 square feet.

How many square feet are in 150 square inches? Let’s divide 150 by 144. It gives 150/144, after reducing it is 25/24. The final result as a decimal is equal 1.04167 square feet.

The last one calculation. How many square feet are in 300 square inches? Divide 300 by 144. It gives 300/144. Now reduce the fraction. It gives 25/12. As a decimal the result is equal 2.083 square feet.

Quite easy, right?

Move on to a little more complicated part. Now we will show you how to calculate from inches to feet and inches.

How many feet and inches are in 30 inches?

·Divide 30 by 12.

30 / 12 = 2.5

·Subtract the decimal portion from the feet to get only feet measurement.

2.5 – 0.5 = 2

·Now multiply the result by 12 to see how many inches it is equal.

2 * 12 = 24

·Then subtract this result from inches which you want to convert.

30 – 24 = 6

·This is your inch measurement.

·So the final result is equal 2 feet and 6 inches. You can also write it as 2’ 6”.


Try make another example. How many feet and inches are in 50 inches?

·Divide 50 by 12.

50 / 12 = 4.17

·Subtract the decimal portion from the feet to get only feet measurement.

4.17 – 0.17 = 4

·Multiply the result by 12 to see how many inches it is equal.

4 * 12 = 48

·Subtract this result from inches which you want to convert.

50 – 48 = 2

·This is your inch measurement.

·The final result is equal 4 feet and 2 inches (4’ 2”).


The last example. How many feet and inches are in 80 inches?

·Divide 80 by 12.

80 / 12 = 6.67

·Subtract the decimal portion from the feet to get only feet measurement.

6.67 – 0.67 = 6

·Multiply the result by 12 to see how many inches it is equal.

6 * 12 = 72

·Subtract this result from inches which you want to convert.

80 – 72 = 8

·This is your inch measurement.

·The final result is equal 6 feet and 8 inches (6’ 8”).
