MyEstimate

Use this calculator to find the square footage and square meters for different types of projects. Calculate square footage, meters for flooring, carpet or tiling(countertop, roundtables) projects to estimate area and the amount of material you will need. Also, calculate the cost of materials when you enter the price per square foot or price per square meter.
Enter measurements in US units or metric units. Calculate area from your measurements in feet (ft) or meters (m). You can also enter decimal values. For example, if you have one measurement that is 103" you can enter that as 10.25 feet (3"/12" = 0.25 ft). If you have a measurement of 325 cm you can also enter that as 3.25 m. Example:
12" = 1
9" = 0.75
6" = 0.5
3" = 0.25
