Calculate Lenght
The Feet and Inches Length Calculator is a practical tool for converting measurements between feet and inches, as well as for calculating total lengths. This calculator is especially useful in various fields such as construction, carpentry, interior design, and everyday activities where precise measurements are essential. By using this calculator, you can easily convert and add lengths expressed in feet and inches, making your measurement tasks more efficient.
How to Use the Feet and Inches Length Calculator
Using the Feet and Inches Length Calculator is straightforward. You simply input the length in feet and inches, and the calculator will provide the total length in inches, feet, or other desired units. You can also use it to convert lengths from inches to feet.
Conversion Formulas
- Feet to Inches: Length (in)=Length (ft)×12\text{Length (in)} = \text{Length (ft)} \times 12Length (in)=Length (ft)×12
- Inches to Feet: Length (ft)=Length (in)12\text{Length (ft)} = \frac{\text{Length (in)}}{12}Length (ft)=12Length (in)
- Adding Feet and Inches: Total Length (in)=(Feet×12)+Inches\text{Total Length (in)} = (\text{Feet} \times 12) + \text{Inches}Total Length (in)=(Feet×12)+Inches

Detailed Explanation of Calculations
To help you understand how to arrive at the length calculations, let’s break down a few examples in detail:
- Example 1 – Single Measurement of 5 Feet 8 Inches:
- Formula Used: Total Length = (Feet × 12) + Inches
- Calculation:
- Total Length = (5 × 12) + 8 = 60 + 8 = 68 inches.
- Conversion to Feet:
- Total Length in feet = 68 / 12 = 5.67 feet.
- Application: This calculation is ideal for measuring a board that is 5 feet 8 inches long for a woodworking project.
- Example 2 – Adding Lengths of 3 Feet 4 Inches:
- Formula Used: Total Length = (Feet × 12) + Inches
- Calculation:
- Total Length = (3 × 12) + 4 = 36 + 4 = 40 inches.
- Conversion to Feet:
- Total Length in feet = 40 / 12 = 3.33 feet.
- Application: Useful for adding lengths when planning a fence section measuring 3 feet 4 inches.
- Example 3 – Single Measurement of 6 Feet 2 Inches:
- Formula Used: Total Length = (Feet × 12) + Inches
- Calculation:
- Total Length = (6 × 12) + 2 = 72 + 2 = 74 inches.
- Conversion to Feet:
- Total Length in feet = 74 / 12 = 6.17 feet.
- Application: This calculation is suitable for measuring the height of a door at 6 feet 2 inches.
- Example 4 – Adding Lengths of 2 Feet 10 Inches:
- Formula Used: Total Length = (Feet × 12) + Inches
- Calculation:
- Total Length = (2 × 12) + 10 = 24 + 10 = 34 inches.
- Conversion to Feet:
- Total Length in feet = 34 / 12 = 2.83 feet.
- Application: Ideal for adding lengths when calculating the total height of a window treatment at 2 feet 10 inches.
- Example 5 – Single Measurement of 4 Feet 6 Inches:
- Formula Used: Total Length = (Feet × 12) + Inches
- Calculation:
- Total Length = (4 × 12) + 6 = 48 + 6 = 54 inches.
- Conversion to Feet:
- Total Length in feet = 54 / 12 = 4.50 feet.
- Application: Great for measuring the width of a table at 4 feet 6 inches.
- Example 6 – Adding Lengths of 5 Feet 3 Inches:
- Formula Used: Total Length = (Feet × 12) + Inches
