Cubic Yard Calculator


Pouring concrete for a slab

A cubic yard is the volume of material which fits in a space one yard wide by one yard deep by one yard high. Cubic yards are used to measure materials ranging from concrete to mulch for your garden.

Common materials that are measured in cubic yards include:

  • Concrete
  • Gravel
  • Sand
  • Rock
  • Fill dirt
  • Topsoil
  • Mulch
  • Compost

To determine the amount of materials you need in cubic yards, you must first convert all three dimensions to the same unit of measurement. There are:

  • 27 cubic feet in one cubic yard (3’ x 3’ x 3’)
  • 46,656 cubic inches in one cubic yard (36” x 36” x 36”)

For example, to find the amount of concrete needed for a slab 6” thick by 12’ long by 12’ wide:

  1. Convert the dimension in inches to feet (6” ÷ 12” = 0.5’)
  2. Multiply the three dimensions together to find the number of cubic feet (0.5’ x 12’ x 12 = 72 cubic feet)
  3. Divide the cubic feet by the number of cubic feet in a cubic yard (27) to find the number of cubic yards (72 ÷ 27 = 2.67 cu. yd.).

You can find the same result by converting all three dimensions to yards by:

  1. Convert the dimension in inches to yards (6” ÷ 36” = 0.167 yards)
  2. Convert the dimensions in feet to yards (12’ ÷ 3 = 4 yards)
  3. Multiply the three dimensions together to find the number of cubic yards (0.167 x 4 x 4 = 2.67 cu. yd.)

Or, simply input your dimensions in our handy calculator below, then click “calculate” to find the number of cubic yards.

    Thank you. I’ve been calculating these measurements every few years. But not enough to hold the formulas in my head. Now I have to figure out the square yards of the trapazoid for this project. Thank you again.

    I am filling 16 in. casing or Pilon with sand how do I come up with the yards of Sand I need to do this Job

    Calculate the volume of a cylinder. It works out to 1.4 cubic feet of sand for every foot of length of the casing. A yard of sand is 27 cubic feet, divided by the 1.4 cu/ft = 19 feet of 16″ casing can be filled with a yard of sand.

    I live in a hillside area and they are building a lot down the street from me. They expect to remove 1,735 cubic yards of earth and anticipate taking 20 full days to do so. Can anyone give me an idea of how many builder’s dump trucks will be passing by my house in total?

    Irene I think you will need about 115 dump truck loads each one will have about 15 yards a truck if it’s a random ten wheel truck

    Am stockpiling sand on a land That’s length is 1000 meters by 500 meters wide, and height of the sand is 30 ft. How do I calculate the amount of sand in place…
