Understanding Countertop Square Footage Calculation

Countertops are typically measured in square feet, but dimensions are often taken in inches. The Countertop Square Footage Calculator simplifies this by converting the length and width (in inches) into square footage. Here's the step-by-step formula.

The Formula for Countertop Square Footage

The formula for calculating countertop square footage is:

$\text{Square Footage} = \frac{\text{Length (inches)} \times \text{Width (inches)}}{144}$

Breaking Down the Formula

Length and Width in Inches: Measure the length and width of the countertop in inches.

Conversion Factor (144): Since one square foot equals 144 square inches, divide the total area (in square inches) by 144 to convert it into square feet.

Square Footage: The final value is the total area of the countertop in square feet.

Example Calculation

Let’s calculate the square footage of a countertop with a length of 72 inches and a width of 36 inches.

Step 1: Multiply Length and Width (in inches)

$\text{Area (sq. inches)} = \text{Length} \times \text{Width}$

$\text{Area (sq. inches)} = 72 \, \text{in} \times 36 \, \text{in} = 2592 \, \text{sq. in}$

Step 2: Convert to Square Feet

$\text{Square Footage} = \frac{\text{Area (sq. inches)}}{144}$

$\text{Square Footage} = \frac{2592 \, \text{sq. in}}{144} = 18 \, \text{sq. ft}$
