How to Convert Cubic Feet to Cubic Inches

Conversion Formula

Cubic Inches = Cubic Feet × 1,728

To convert a volume from cubic feet to cubic inches, multiply the cubic feet value by 1,728. This is because 1 foot equals 12 inches, and for cubic measurements:

1 ft³ = (12 in)³ = 12³ in³ = 1,728 in³

Step-by-Step Example

Converting 5 cubic feet to cubic inches:

Start with the cubic feet value: 5 ft³
Multiply by the conversion factor: 5 ft³ × 1,728 = 8,640 in³
Result: 5 cubic feet equals 8,640 cubic inches

What is a Cubic Foot?

A cubic foot (ft³) is a unit of volume in the imperial and US customary systems. It represents the space occupied by a cube with sides that are each 1 foot in length.

A cubic foot is commonly used for measuring:

Construction materials (concrete, timber)
Shipping and freight volume
Interior space in rooms
Natural gas volume
Refrigerator capacity

One cubic foot is approximately equal to 28.3168 liters or 0.0283168 cubic meters.

What is a Cubic Inch?

A cubic inch (in³) is a unit of volume in the imperial and US customary systems. It represents the space occupied by a cube with sides that are each 1 inch in length.

Cubic inches are commonly used for measuring:

Small electronic devices
Engine displacement in automobiles
Small packages and containers
Jewelry boxes and small storage
Computer components

One cubic inch is approximately equal to 16.387 milliliters or 0.016387 liters.

Practical Applications

Shipping and Packaging

When calculating shipping costs or packaging requirements, understanding the volume in both cubic feet and cubic inches is essential. Many shipping carriers base their rates on dimensional weight, which requires accurate volume measurements.

Example: A package measuring 2 ft × 1.5 ft × 1 ft has a volume of 3 cubic feet or 5,184 cubic inches.

Construction and Engineering

For construction projects, materials like concrete are often quoted in cubic yards or cubic feet, while detailed component measurements might be in cubic inches. Converting between these units helps coordinate between different aspects of a project.

Example: A concrete slab measuring 10 ft × 8 ft × 0.5 ft requires 40 cubic feet of concrete, which equals 69,120 cubic inches.
