How to convert square feet to cubic yards

It is important to know the entire surface of an area before beginning repairs. Sometimes it is necessary to go a step further and determine the volume of the room, that is - the cubic meters . Since a cubic meter and yards are measured in three dimensions and the square footage measures two dimensions, there is no simple formula for conversion. But if you know the area you need to measure, you can do some quick calculations to find out.

one

Know the difference between a three-dimensional measurement and a two-dimensional measurement. The square feet are calculated having only the flat surface in mind. That is a two-dimensional measure. The feet and cubic meters are calculated using the length, width and depth (or height). This adds the third dimension and makes it a measure of volume. The best way to think is as if you are calculating how much of something is needed to fill a box.

two

Determine the number of square meters you are working. The square footage of a space is essentially its area, which means you will have to multiply the length by the width. For example, a room that is 10 feet long and 12 feet wide will be calculated as follows: 10 feet x 12 feet = 120 square feet

Add the third dimension. Sometimes this will be as easy as measuring the height of a wall or the depth of a flower bed, but sometimes it is a little more complicated. If you need to know are cubic yards to buy items such as topsoil, which are measured as such, then determine the depth of the soil bed you want. This can be your third dimension. For example, if you want to fill your aforementioned room with topsoil 2 feet deep, the calculation would be: (10 feet long) x 120 feet (wide) x 2 feet (depth) = 240 cubic feet

Convert cubic feet to cubic yards . There are 27 feet in a cubic yard. Therefore to determine cubic yards, divide the cubic feet by 27. For example: 240 feet / 27 cubic = 8.8 cubic meters. Tips and warnings Convert all numbers to the same measurement. You can not multiply feet by inches and get an accurate measurement. If you would like to fill the room with topsoil 4 inches deep, then you need to convert 4 feet to inches (0.3).
