Convert Inches to Feet – Introduction

Inches and feet are common measurements of lengths that you will encounter when measuring lengths, widths and heights. It is important to understand these units and to be able to convert between them. In this text, we’ll dive deeper into the conversion of these units of measurement. We’ll look at how to convert inches to feet and feet to inches and look at examples of guided conversions.

Inches and Feet – Revision

Let’s repeat what inches and feet are and how they are used by revising the definition:

Both inches and feet are used to measure length, width and height – which are all distances. Inches are smaller units than feet and are used to measure shorter lengths or distances. Feet, on the other hand, are used to measure longer distances, and 1 foot is made up of 12 inches.

Converting Feet to Inches

If we know that 1 foot is made up of 12 inches, this is the conversion rate for feet to inches. We can use this information to change from inches to feet and from feet to inches. To change from feet to inches:

Step 1: Create a ratio table

Write 1 in the ‘Feet’ column and 12 in the ‘Inches’ column to show that 12 inches is the same as 1 foot. Notice to convert from feet to inches you need to multiply the number of feet by 12.

Step 3: Now place the feet that you want to convert into inches in the ‘Feet’ column and multiply it by 12 to convert into inches.

To convert feet to inches, we can follow these steps:

Step # What to do
1 Create a ratio table and label the
first column “feet” and
the second column “inches”
2 Write 1 in the feet column and 12
in the inches column to show that
1 foot is 12 inches
3 Write the number of feet that you
need to convert in the ‘Feet’ column
4 Multiply by 12 to calculate
the number of inches in each foot

Feet to Inches – Conversion Table

It can be helpful to have a conversion table with some common conversions of feet and inches. Below you will find a conversion table for an overview.

Feet Inches
1 12
5 60
6 72
20 240

Converting Inches to Feet

To convert inches to feet, set up a ratio table like the one before. However, this time, place the inches in the ‘Inches’ column. Then, use the opposite operation to calculate the number of feet. Since the opposite operation of multiplication is division, we divide. For example, if we want to convert 60 inches to feet, we place the 60 in the ‘Inches’ column and divide by 12.

Feet (ft) Inches (in)
1 12
3 36
60 ÷ 12

The quotient of 60 and 12 is five, so 60 inches is 5 feet.

Feet (ft) Inches (in)
1 12
3 36
5 60 ÷ 12

Transcript Converting Inches and Feet

"All right Zuri, I think we have everything we need to make the superhero costumes." "I can not believe you found that magic fabric just sitting there!" "Just one thing, it seems like the sewing instructions are explaining the steps using inches and feet." Let's help Zuri and Freddie make their superhero costumes by converting inches and feet. When we measure length, width, or height, we can measure using inches and feet in the same way that we can use centimetres and metres. An inch is a small unit of length that is approximately equal to two and a half centimetres. When we write inches, we can abbreviate using the letters . We can use inches to measure smaller objects, like this piece of cheese. A foot is a unit of length that is larger than an inch and is approximately equivalent to thirty centimetres. When we write feet, we can abbreviate using the letters . Feet and inches are sometimes used when measuring peoples' heights. When we measure with inches and feet we can use a ruler or measuring tape. Sometimes we need to convert, or change, feet to inches and inches to feet. One foot is equal to twelve inches, and twelve inches is equal to one foot. We can use a ratio table to help us write our conversions. To set up the ratio table, first label feet on one side and inches on the other. One foot is twelve times bigger than one inch. That means to convert feet to inches, we multiply by twelve. Write times twelve next to the foot we are converting and solve. One times twelve is twelve, so there are twelve inches in one foot. Zuri and Freddie need to convert the first piece of fabric, which is three feet long, to inches. Write three under the feet column here. How many inches is three feet? Remember, one foot is twelve inches, so we multiply three times twelve. Three times twelve is thirty-six, so they need thirty-six inches of the magic fabric. The next piece of fabric is sixty inches long, this time they need to convert inches to feet. How can we do this? We can solve for feet by using the inverse, or opposite, operation. The inverse operation of multiplication is division, so we divide sixty inches by twelve. What is sixty divided by twelve? Sixty divided by twelve is five. That means they need five feet of the magic fabric. While Zuri and Freddie finish making their costumes, let's remember. Sometimes we need to convert, or change, feet to inches and inches to feet. One foot is equal to twelve inches, and twelve inches is equal to one foot. We can use a ratio table to help us write our conversions. To set up the ratio table, first label feet on one side and inches on the other. Finally, multiply by twelve to convert feet to inches or divide by twelve to convert inches to feet. "These superhero costumes are awesome, check this out Zuri!" "Yeah Freddie, they're super!" "I guess my superpower is going to be very useful!"
