# How do you calculate the cubic feet of a refrigerator?

Asked by essieness (7693) March 15th, 2009

I’m having this argument with my family… I think I’m right, but they think they’re right. They have a fridge they’re trying to sell and they want to be able to tell prospective buyers how big it is. Here are the measurements:

32” by 62” by 30”

Don’t you multiply them all together to get the result in cubic inches? Then, can’t you just divide that number by 12 to get the answer in cubic feet?

Did your family pass high school maths?

I kid.

Haha, Thanks!

essieness (7693)

Anytime, kiddo.

No, because 1 cubic foot does not equal 1 cubic inch. 1 cubic foot equals 1728 cubic inches (12×12x12).

32”*62”*30” = 59,520 cubic inches
59,520 cubic inches / 1728 cubic inches = 34.4444 cubic feet.

@critter1982 Thanks, that site that @asmonet suggested told me that :)

Don’t you go one-upping me Jayne. I see you craftin’ responses and whatnot.

asmonet (21370)

Yeah she beat me to it, I figured if I didn’t read the page I could plead the fifth. ;)

No, no, no, you have it all wrong. You have to lower the appliance onto its back and fill the interior with water (after waiting for the interior to warm to room temperature, of course, to avoid cooling the water). Allow enough time for the water to settle before topping off the water level. Then empty the fridge of water, measuring the volume removed with a graduated cylinder. Work quickly, or the effects of evaporation will lead to an underestimate. Next, fill a large drum with water, using the same graduated cylinder to mark off volumetric increments corresponding to your desired margin of error. Then empty the drum halfway, and use the principle of water displacement to measure the volumes of any items that were in the fridge. If an item is porous, make sure that all water contained therein evaporates before determining its volume. Add the summation of these volumes to the volume of water that fit into the loaded fridge, and voila. Wasn’t that easy?

Is it sad that I totally imagined her doing the water thing before I googled? I kinda wanted to see if she’d try it. XD

Yes, asmonet, it is very sad. I honestly have no idea what could have been going through your head. You should be ashamed of yourself.

Simply tell people in the ad that the frizzer can easily accommodate a body. Who needs exact?
