Enter the interior dimensions of your refrigerator (in inches) to calculate its total cubic feet capacity.
Understanding Refrigerator Cubic Feet Capacity
The capacity of a refrigerator is typically measured in cubic feet, representing its total internal volume. This measurement helps consumers understand how much food and storage space a particular model offers. Calculating this value is a straightforward application of basic geometry, allowing you to understand the storage potential of your appliance.
The Formula for Volume
The volume of any rectangular prism (like the interior of a refrigerator) is calculated by multiplying its three dimensions: depth, width, and height.
The formula is:
Volume (cubic inches) = Depth × Width × Height
Converting Cubic Inches to Cubic Feet
Since refrigerator capacities are commonly stated in cubic feet, we need to convert our result from cubic inches. There are 12 inches in a foot, so there are 12 × 12 × 12 = 1728 cubic inches in one cubic foot.
Therefore, to convert cubic inches to cubic feet, we divide the volume in cubic inches by 1728:
Our calculator simplifies this process for you. Simply input the interior measurements of your refrigerator (or a specific compartment like the freezer or fridge section) in inches for depth, width, and height. The calculator will then automatically compute and display the total capacity in cubic feet.
Why is Cubic Feet Important?
Storage Planning: Knowing the cubic feet helps you estimate if a refrigerator meets your household's food storage needs.
Appliance Comparison: It's a standard metric used to compare different refrigerator models side-by-side.
Space Utilization: Understanding capacity can also give you an idea of how efficiently space is designed within the appliance.
Whether you're buying a new refrigerator, trying to organize your current one, or simply curious about its capacity, this calculator provides a quick and accurate way to determine its volume in cubic feet.

resultDiv.innerHTML = 'Please enter valid positive numbers for all dimensions.';
return;
}
// Calculate volume in cubic inches
var volumeCubicInches = depth * width * height;
// Convert to cubic feet
var volumeCubicFeet = volumeCubicInches / 1728;
// Display the result
resultDiv.innerHTML = volumeCubicFeet.toFixed(2) + ' cubic feet';
