How to Convert Inches to Cubic Ft

Question asked by Gloria:

I am trying to calculate the size of my refrigerator so that I can purchase another one of the same size. My husband measured my current fridge in inches.

My fridge measures 64" height x 28" width x 29" depth. Can you please tell me how to calculate the cubic feet?

Hi Gloria,

There are a couple of steps involved here, as inches are a unit of length and cubic feet are a unit of volume. So, we need to get a cubic inch volume figure first and then convert that figure into cubic feet.

Here's the process...

  1. We start by multiplying your inches measurements together to get a cubic inches figure. So, 64 x 28 x 29 = 51968 cubic inches.
  2. To convert cubic inches to cubic feet we divide the figure by 1728 (there are 1728 cubic inches in a cubic foot).

    51968 / 1728 = 30.074 cubic feet.
I have a handy cubic feet calculator here that will do the whole process for you, should you wish to use it. I've also published a detailed article about how to calculate cubic feet here.
