Carpet Measurement Formula Explained

The calculator uses basic geometry and conversion formulas.

1. Area in Square Feet

$A = L \times W$ A=L×W

Where:

A = Area (sq ft)
L = Length (feet)
W = Width (feet)

This is the most basic formula for calculating rectangular space.

2. Conversion to Square Meters

$1\ \text{sq ft} = 0.092903\ \text{m}^2$ 1 sq ft=0.092903 m2

So,

$A_{m^2} = A_{ft^2} \times 0.092903$ Am2=Aft2×0.092903

This allows you to convert imperial measurements into metric units.

3. Carpet Cost Estimation

$C = A \times r$ C=A×r

Where:

C = Total cost
A = Area in square feet
r = Cost per square foot

In this tool, a default value of $5 per sq ft is used as an example.

Example Calculation

Let’s understand this with a real-life example.

Room Dimensions:

Length = 12 feet
Width = 10 feet

Step 1: Calculate Area

Area = 12 × 10 = 120 sq ft

Step 2: Convert to Square Meters

120 × 0.092903 = 11.15 m²

Step 3: Estimate Cost

If carpet cost is $5 per sq ft:

120 × 5 = $600

Final Result:

Area = 120 sq ft
Area = 11.15 m²
Estimated cost = $600
