# Conversion of Volume

*Note: we also have Conversion Charts, and a Unit Converter*.

First, you should understand Conversion of Length. If you are comfortable converting miles to kilometers, etc, then you are half way there.

## Volume is Length by Width by Height

To convert Volume, remember that **volume is length by width by height**:

Volume = Length × Width × Height

So, we need to convert *once for the length* and *once again for the width* and *once more for the height*. It is that easy:

Just do the length conversion three times.

Here are some examples:

### Example: Convert 1 cubic yard into cubic feet.

Now, we know that three feet make a yard:

1 yd = 3 ft

So, the **Length** conversion is "multiply by 3".

And so the **Volume** conversion must be to multiply by 3 and multiply by 3 *again* and then multiply by 3 *once again* (ie once each for length, width and height)

The result is:

3 × 3 × 3 = 27

**There are 27 cubic feet in a cubic yard.**

Try to count the 1 ft cubes below, and you will see why:

### Example: Convert 30 cubic feet into cubic meters (30 ft^{3} to m^{3})

The conversion for feet to meters is:

1 ft = 0.3048 m

So, the **Length** conversion is to multiply by 0.3048

And the **Volume** conversion must be to multiply by 0.3048, and multiply by 0.3048 and multiply by 0.3048 again:

30 × 0.3048 × 0.3048 × 0.3048 = 0.85

So, **30 ft ^{3} = 0.85 m^{3}**
