If you have ever ordered materials like concrete, dirt, or mulch, you know the pain: you measured the square footage, but the supplier demands cubic yards. It is like speaking two different languages. This calculator translates for you instantly. No more complicated manual division, just the volume you need to buy.

Area to Volume is Simple

1. The Two Key Inputs: Area and Depth

You only need two numbers to use this tool. Think of it as painting a floor (area) and then filling that floor up (height/depth).

• Square Feet (Area): This is the length times the width of the space you are working on. Input the total ft2 of your area here. For example, if your room is 10 feet by 10 feet, the area is 100.
• Height/Depth (Feet): This is the third dimension. If you are filling a pit, enter the depth. If you are measuring a room for air conditioning, enter the room height. Make sure this number is in feet.

The second you enter both numbers, the results pop up. Exactly, no need to click "Calculate."

2. The Results: Cubic Measurements You Need 

The calculator quickly gives you the two common volume units. Volume is what you measure materials by, unlike area which is just the flat ground.

• Cubic Feet (ft3): This is the immediate result of multiplying your area by your depth. This is used for small projects or when calculating air volume.
• Cubic Yards (yd3): This is the number you usually need for large outdoor materials like gravel, mulch, or concrete. Suppliers almost always quote prices in yd3.

The calculator simply divides the ft3 by 27 because 27 cubic feet fit into one cubic yard. Now you can order materials with total confidence.

3. Quick Reference 

Remember the core idea:

Volume = Area x Height

If you have 100sq ft and a depth of 2ft, the volume is 200 cubic feet. The calculator takes this 200 and divides it by 27 to tell you exactly how many cubic yards you need. This saves time and money by preventing over-ordering.
