Formula used
Rectangular box: V = L × W × H
Cylinder: V = π × r² × h where r = diameter ÷ 2
Conversions:
- 1 m = 100 cm = 1000 mm = 3.28084 ft = 39.3701 in
- 1 m³ = 1000 liters ≈ 35.3147 ft³ ≈ 61023.7441 in³
How to use

Frequently asked questions
A cubic meter (m³) measures volume equal to a cube one meter on each side. It is commonly used for materials storage containers fluid capacity and space planning.
Yes. Choose a unit for length width or diameter and height independently. The calculator converts each to meters before computing volume.
Standard engineering factors are used: 1 ft = 0.3048 m and 1 in = 0.0254 m. You can adjust decimal places with the precision control.
For cylinders the second input represents diameter. The radius is half of the diameter which the formula uses to compute cross sectional area.
