| From: | To: |
Feet and inches addition is a method of adding two imperial length measurements. Since 1 foot equals 12 inches, any sum of inches that exceeds 11 must be converted to feet with the remainder staying as inches.
The calculator uses the formula:
Where:
Explanation: The calculator adds the feet values together, adds the inch values together, then converts any inches over 11 to feet (carry over) and adds them to the total feet.
Details: Accurate addition of feet and inches is crucial in construction, interior design, carpentry, and any field that uses imperial measurements for precise calculations.
Tips: Enter whole numbers for feet (0 or greater) and inches (0-11). The calculator will automatically handle the conversion from inches to feet when the inch total exceeds 11.
Q1: Why convert inches to feet when adding?
A: Since 12 inches equal 1 foot, any measurement with 12 or more inches should be converted to the appropriate number of feet plus the remaining inches for proper formatting.
Q2: Can I add more than two measurements?
A: This calculator is designed for two measurements. For more measurements, you would need to add them in pairs or use a different tool.
Q3: What about fractional inches?
A: This calculator uses whole inches only. For fractional inches, you would need to convert fractions to decimals first.
Q4: Can I use this for subtraction as well?
A: No, this calculator is specifically designed for addition. Subtraction requires different handling, especially when the second measurement has more inches than the first.
Q5: Why is there a maximum of 11 inches?
A: Since 12 inches equals 1 foot, any value of 12 or more inches should be entered as feet instead. This maintains proper measurement formatting.
