Our square footage calculator helps to calculate the measurement of area for different common shapes. It provides results in terms of various units, including square footage, square inches, square meters, and square yardage.
The calculator is very useful for anyone who wants to calculate area for various projects like gardening, flooring, landscaping, tiling, etc.
Steps to using the calculator include:
It defines the measurement of a square area with all sides equal to 1 foot.
Square footage is an imperial unit of area. It is a non-SI and non-metric unit and is used in the United States, UK, India, Nepal, Liberia, Pakistan, Ghana, Myanmar, Bangladesh, Singapore, Malaysia, and Hong Kong.
Steps to calculate square footage include:
Take a measuring tape and start measuring the length and width of the area under observation.
If you took measurements in other units (say inch, meter, centimeter, etc.), convert them to equivalent feet measurements. For reference, the following table contains an equivalent measurement of 1 square foot:
| Square Footage | Other Unit Conversion |
|---|---|
| 1 square foot (ft²) | 0.000022956341 acres (ac) |
| 1 square foot (ft²) | 0.000009290304 hectare (ha) |
| 1 square foot (ft²) | 0.09290304 square meters (m²) |
| 1 square foot (ft²) | 144.0000002229 square inches (in²) |
| 1 square foot (ft²) | 0.111111106982 square yards (yd²) |
| 1 square foot (ft²) | 929.0304014422 square centimeters (cm²) |
| 1 square foot (ft²) | 9.290304 square decimeters (dm²) |
| 1 square foot (ft²) | 0.00000009290304 square kilometers (km²) |
| 1 square foot (ft²) | 144003673094580 square microinches (µin²) |
| 1 square foot (ft²) | 92903040000 square micrometers (μm²) |
| 1 square foot (ft²) | 0.0000000358701 square miles (mi²) |
| 1 square foot (ft²) | 92903.04 square millimeters (mm²)(ac) |
Once you convert all units to the measure of feet, use the following formula:
Area (Square Footage) = Length (ft) * Width (ft)
\(Area\left(ft^{2}\right) = \text{Side Length} * \text{Side Length}\)
\(Area\left(ft^{2}\right) = Length * Width\)
\(\text{Inner Area} \left(ft^{2}\right) = Length * Width\) \(\text{Total Area} \left(ft^{2}\right) = \left(Length + \left(2 * \text{Border Width}\right)\right)\) \(Area\left(ft^{2}\right) = \text{Total Area} - \text{Inner Area}\)
\(Area \left(ft^{2}\right) = \pi * \left(\frac{Diameter}{2}\right) ^ {2}\)
\(\text{Outer Diameter} = \text{Inner Diameter} + \left(2 * \left(\text{Border Width}\right)\) \(\text{Outer Area} \left(ft^{2}\right) = \pi * \left(\frac{\text{Outer Diameter}}{2}\right) ^ {2}\) \(\text{Inner Area} \left(ft^{2}\right) = \pi * \left(\frac{\text{Inner Diameter}}{2}\right) ^ {2}\) \(Area \left(ft^{2}\right)= \text{Outer Area} - \text{Inner Area}\)
\(Area \left(ft^{2}\right) = \left(\frac{\left(a + b\right)}{2}\right) * h\)
\(Area \left(ft^{2}\right) = Base * Height\)
\(Area \left(ft^{2}\right) = \left(\frac{1}{4}\right) * \sqrt{\left(a + b + c\right) * \left(b + c - a\right) * \left(c + a - b\right) * \left(a + b - c\right)}\)
Or even:
\(Area \left(ft^{2}\right) = \frac{1}{2} * b * h \((When base and height of the triangular area is involved)
\(Area \left(ft^{2}\right) = \pi * \text{Major Axis} * \text{Minor Axis}\)
\(Area \left(ft^{2}\right) = \text{Area Of Sector} = \frac{\alpha * r^{2}}{2}\)
\(Area \left(ft^{2}\right) = \frac{3\sqrt{3}}{2} * a^{2}\)
\(Area \left(ft^{2}\right) = 2 * \left(1 + \sqrt{2}\right) * a^{2}\)
\(\text{Outer Area} \left(ft^{2}\right) = \pi * \left(\frac{\text{Outer Diameter}}{2}\right) ^ {2}\) \(\text{Inner Area} \left(ft^{2}\right) = \pi * \left(\frac{\text{Inner Diameter}}{2}\right) ^ {2}\) \(Area \left(ft^{2}\right) = \text{Outer Area} - \text{Inner Area}\)
Calculating square footage tailored to the above formulas can consume time. The square footage calculator makes this calculation fast, accurate, and easy to understand. It can handle all the shapes mentioned above.
Let’s calculate the square footage of a rectangular room with the following dimensions: Length = 100 ft Width = 219 ft
\(Area\left(ft^{2}\right) = Length * Width\)
\(Area\left(ft^{2}\right) = 100 ft * 219 ft\) \(Area\left(ft^{2}\right) = 21,900\)
Formula: Total Material Cost = Material Price per Square Foot * Total Square Footage
