The recipe is simple: input the value of your choice in any format you want. You may enter:

Regular decimals (e.g., $2.5$);

Fractions & divisions (e.g., $1/4$, $1/32$);

Integers along with fractions (e.g., $1 + 3/8$, $2 + 4/2$);

Multiplication (e.g. $3 * 4$);

Subtraction (e.g., $4  1$); and

If you value doesn't have feet or inches, enter $0$ into the appropriate box in the calculator.


Your result will depend on the type of calculation you choose. There are four available options:

➕ Add feet and inches
Your result will consist of the calculated feet, inches, and fractional inches to the precision of your choice.

➖ Subtract feet and inches
Your result will consist of the calculated feet, inches, and fractional inches to the precision of your choice.

✖️ Multiply feet and inches
Your result will be shown in both square feet and square inches ($\mathrm{ft^2}$, $\mathrm{in^2}$).

➗ Divide feet and inches
Your results will not have a unit. Why is that? If you divide feet by feet, the identical units are removed, e.g., $\mathrm{ft/ft} = 1$.

Area calculator – feet and inches
You can use our feet and inches tool as a square footage calculator in feet and inches  you just need to choose the multiply option.
Obviously, using this FIS (FootInchSixteenth) calculator is the simplest solution  but what if we wanted to compute the area all by ourselves? As an example, let's estimate the area of a kennel for our dog.

Choose whether you'd like your result to be in square feet ($\mathrm{ft^2}$) or inches ($\mathrm{in^2}$).
In this example, we decided to use square inches.

Convert your values in feet & inches to inches, e.g., with the help of our length converter, which also works as an inches to feet and inches calculator (just select the corresponding units).
Our dog house's walls are 2 feet 6 inches long and 1 foot 5 inches wide. Let's convert feet and inches to inches:

How to add feet and inches?
Our feet and inches calculator's most popular option is add feet and inches. So, if want to find out how to add feet and inches, here's how to do it:
 Let's start with an easy example 😌 :
This equation requires just a simple addition of feet and inches done separately: we're first adding feet $2 + 5 = 7\ \mathrm{ft}$ and then inches $3 + 6 = 9\ \mathrm{in}$.
We then compile the complete result: $7\ \mathrm{ft}\ 9\ \mathrm{in}$.
We only need to make sure that the number of inches is lower than 12 because 12 inches make one foot! This how you can convert inches to feet and inches.
 What about adding inches with fractions? 😮 How to add feet and inches in that case?
 We start by adding feet and inches separately:
12 inches creates an additional foot. We have 4 feet all together.

Now it's time to solve the fractions 1/4 and 9/16.
In order to do that, we need to find the smallest denominator possible for both of these fractions. Firstly, we'll be looking for the least common multiple (LCM).
Our denominators are 4 and 16, so their LCM is 16.
Let's change the denominators so that they're equal to each other and multiply the numerator by the same number as its denominator:
(16/4 = 4; in this case we need to multiply them by 4):
 Since we've already computed the feet and inches, it's time to compile the results:
FAQ
How should I write feet and inches?
We can write the abbreviation for feet as ft – for example, we will write 4 feet as 4 ft. Another way is to write a single apostrophe indicating feet, so 4′ = 4 ft = four feet.
We can write the abbreviation for inches as in. Thus, for ten inches, we will write 10 in. In another way, we can use a double apostrophe – so ten inches we write as 10″.
How many foot are 12 inches?

62 inches are 5 feet and 2 inches (5 ft 1/6 in). To convert 62 inches into feet and inches:
 Divide 62 inches by 12: 62/12 = 5 R 2.
 The quotient (5) is the number of feet and the remainder (2) is the number of inches.
 The answer in feet and inches is 5 ft 2 in.
How can I multiply feet and inches?
Assuming you want to multiply 4 ft 3/8 in by 2 ft, you will get 1161 in². To do it:

Convert 4 feet to inches by multiplying 4 by 12: 4 × 12 = 48.

Add extra inches: 3/8 = 0.375 in, so 48 + 0.375 = 48.375 in.

Convert 2 feet to inches: 2 × 12 = 24.

Multiply by 24: 48.375 × 24 = 1161 in².
