Linear Feet Formula:
| From: | To: |
The conversion from square feet to linear feet calculates the length of material needed when you know the area and width. This is commonly used in construction, flooring, and material estimation projects where materials are sold by linear measurement.
The calculator uses the linear feet formula:
Where:
Explanation: This formula converts area measurement to linear measurement by dividing the total area by the width, assuming uniform width throughout.
Details: Accurate linear feet calculation is essential for material ordering, cost estimation, and project planning in construction, flooring installation, fencing, and other building projects where materials are purchased by linear measurement.
Tips: Enter square footage and width in feet. Both values must be positive numbers. The width must be greater than zero to avoid division by zero errors.
Q1: What's the difference between square feet and linear feet?
A: Square feet measure area (length × width), while linear feet measure length only. Linear feet is used when materials have a fixed width.
Q2: When would I need to convert square feet to linear feet?
A: When purchasing materials like flooring, lumber, countertops, or fencing that are sold by linear foot but you know the total area needed.
Q3: Can I use this for irregular shapes?
A: This calculator assumes uniform width. For irregular shapes, you may need to calculate linear feet for each section separately.
Q4: What if my width is in inches?
A: Convert inches to feet by dividing by 12 before entering. For example, 6 inches = 0.5 feet.
Q5: How accurate is this conversion?
A: The conversion is mathematically precise for rectangular areas with uniform width. Always add 10-15% extra for waste and cutting.
