Cubic Ft Calculator from Inches

Volume Formula:

\[ V_{ft³} = \frac{L \times W \times H}{1728} \]

Volume (ft³):

Definition: This calculator converts measurements in inches to volume in cubic feet.

Purpose: It helps quickly determine the volume of objects or spaces when measurements are taken in inches but the result is needed in cubic feet.

The calculator uses the formula:

\[ V_{ft³} = \frac{L \times W \times H}{1728} \]

Where:

Explanation: The product of length, width, and height in inches is divided by 1728 (12³) to convert to cubic feet.

Details: Accurate volume calculations are essential for shipping, storage, material estimation, and space planning.

Tips: Enter all three dimensions in inches. The calculator will automatically convert to cubic feet. All values must be > 0.

Q1: Why divide by 1728?
A: There are 1728 cubic inches in a cubic foot (12 inches × 12 inches × 12 inches).

Q2: Can I use this for irregular shapes?
A: No, this only works for rectangular prisms. For irregular shapes, use more advanced methods.

Q3: What's the precision of the result?
A: Results are shown to 3 decimal places for most practical applications.

Q4: How do I convert back to inches?
A: Multiply the cubic feet result by 1728 to get cubic inches.

Q5: Can I use fractions of inches?
A: Yes, the calculator accepts decimal values for partial inches.
