Linear Feet Formula:
| From: | To: |
Linear feet calculation converts area measurements (square feet) to length measurements (linear feet) when the width is known. This is commonly used in construction, flooring, and material estimation where materials are sold by linear measurement but coverage is calculated by area.
The calculator uses the linear feet formula:
Where:
Explanation: This calculation assumes uniform width and converts the area measurement into a linear measurement by dividing the total area by the width.
Details: Accurate linear feet calculation is essential for material ordering, cost estimation, and project planning in construction, flooring installation, fencing, and other industries where materials are purchased by linear measurement.
Tips: Enter the total area in square feet and the width in feet. Both values must be positive numbers. The calculator will provide the equivalent linear feet measurement.
Q1: What's the difference between linear feet and square feet?
A: Linear feet measures length in a straight line, while square feet measures area. Linear feet is one-dimensional, square feet is two-dimensional.
Q2: When would I need to convert square feet to linear feet?
A: Common scenarios include ordering flooring, lumber, fencing, countertops, or any material sold by linear measurement but installed over an area.
Q3: Does this calculation work for irregular shapes?
A: No, this calculation assumes a rectangular area with uniform width. For irregular shapes, more complex calculations are needed.
Q4: Should I add extra material for waste?
A: Yes, it's recommended to add 5-10% extra material to account for cutting waste, errors, and future repairs.
Q5: Can I use this for metric measurements?
A: This calculator uses imperial units. For metric, you would convert square meters to linear meters using the same formula with metric measurements.
