What Is a Feet to Inches Calculator?
A Feet to Inches Calculator is a simple tool that converts measurements from feet into inches or inches into feet.
It is based on a fixed rule:
1 foot = 12 inches
The calculator automates the conversion so users do not have to multiply or divide manually.
Most calculators support three main types of conversions:
- Decimal feet to inches
- Feet and inches to total inches
- Inches to decimal feet
Your calculator supports all three modes, which makes it useful for both simple and detailed measurements.
Why Convert Feet to Inches?
Feet and inches are both units of length in the imperial measurement system. However, some tasks require measurements in inches rather than feet.
Here are common situations where conversion is needed:
- Measuring height
- Furniture dimensions
- Room measurements
- Construction and carpentry work
- Engineering drawings
- DIY home projects
For example, a blueprint might list a measurement as 5.5 feet, but a carpenter may need the value in inches.
Using a calculator saves time and reduces mistakes.
Feet to Inches Conversion Formula
The conversion formula is simple.
Convert Feet to Inches
Multiply the number of feet by 12.
Formula
Feet × 12 = Inches
Example
5 feet × 12 = 60 inches
If the value includes decimals:
5.75 feet × 12 = 69 inches
Convert Feet and Inches to Total Inches
When a measurement is written as feet and inches, convert the feet first and then add the extra inches.
Formula
(Feet × 12) + Inches = Total Inches
Example
5 ft 8 in
(5 × 12) + 8
60 + 8 = 68 inches
Convert Inches to Feet
To convert inches to feet, divide the value by 12.
Formula
Inches ÷ 12 = Feet
Example
72 inches ÷ 12 = 6 feet
Decimal feet can also be converted into feet and remaining inches.
Example:
70 inches ÷ 12 = 5.83 feet
Which equals approximately:
5 ft 10 in
How to Use the Feet to Inches Calculator
Your calculator provides three conversion modes. Each mode is designed for a different type of measurement.

Steps:
- Select Feet & Inches to Total Inches
- Enter the whole feet value
- Enter additional inches
