Cubic Feet Calculator

Calculate cubic feet, cubic yards, and cubic meters for shipping, construction, and storage.

उपयोग कैसे करें

Enter length, width, and height to compute volume in cubic feet, cubic yards, and cubic meters — plus a quick estimate of concrete bags needed.

How do I calculate cubic feet?

Cubic feet = Length × Width × Height (all in feet). You can enter other units (inches, meters, cm) and the calculator will convert for you.

How many cubic feet in a cubic yard?

1 cubic yard = 27 cubic feet. The calculator shows both values automatically.

How many 80lb bags of concrete fill 1 cubic foot?

An 80lb bag of concrete mix yields about 0.6 cubic feet when cured. The calculator rounds bag estimates up to whole bags.

Calculate the volume of any rectangular prism in cubic feet, yards, and meters.

ft³ = L(ft) × W(ft) × H(ft)

Volume is the product of length, width, and height in feet.

Example:

Input: 4 ft × 3 ft × 2 ft

Calculation: 4 × 3 × 2

Result: 24 ft³

yd³ = ft³ ÷ 27

1 cubic yard equals 27 cubic feet.

Example:

Input: 54 ft³

Calculation: 54 ÷ 27

Result: 2 yd³

Determine a package's volume for freight pricing.

Estimate how many 80 lb bags of concrete to buy.

Convert all dimensions to feet before multiplying.
An 80 lb bag of concrete yields about 0.6 ft³ — round your bag count up to whole bags.
