Volume Converter is an easy-to-use online calculator that helps you find the volume of any rectangular object by entering its length, width, and depth. It instantly converts the calculated volume into multiple units such as cubic meters (m³), cubic feet (ft³), and cubic centimeters (cm³).
This tool is useful for students, teachers, engineers, builders, and anyone who needs quick and accurate volume calculations for boxes, rooms, containers, or solid shapes.
The volume is calculated using the standard formula:
Volume = Length × Width × Depth
You simply enter the values, select the unit, and the calculator does the rest automatically.
Enter the Length of the object.
Enter the Width of the object.
Enter the Depth (Height) of the object.
Select the unit (Centimeters or Meters).
Click the Calculate button.
Use the dot switches below the result to view the volume in:
Meters Cubed (m³)
Cubic Feet (ft³)
Cubic Centimeters (cm³)
The result updates instantly when you switch between units.

If:
Length = 100 cm
Width = 100 cm
Depth = 100 cm
Then:
Volume = 1 m³
Volume = 35.3147 ft³
Volume = 1,000,000 cm³
Volume measurement has existed for thousands of years:
Ancient Egyptians measured grain storage in cubic containers.
Romans used volume units for trade (wine, oil, grain).
Modern cubic measurements developed with geometry and later the metric system (1790s).
The formula Length × Width × Depth comes from basic solid geometry for rectangular prisms — one of the earliest studied 3D shapes.
Field Why Volume Matters
Construction Concrete, soil, excavation
Shipping Box & container capacity
Aquariums Water tank size
Fuel storage Tank volume
Interior design Room capacity
Cubic meters (m³) → global engineering standard
Cubic feet (ft³) → used in USA construction & appliances
Cubic centimeters (cm³) → used in medicine & engines
If you don’t have a calculator:
1 cubic meter ≈ 35.3 cubic feet
1 cubic meter = 1,000,000 cubic centimeters
Room volume ≈ floor area × ceiling height
Your tool gives exact values — these are quick estimates.
Your calculator works because a rectangular object is a rectangular prism.
The formula applies to:
Boxes
Rooms
Containers
Tanks
For cylinders or spheres, different formulas are needed (πr²h, etc.), which many basic calculators don’t explain.
Q1: What is volume?
Volume measures how much 3D space an object occupies.
Q2: Why do we use cubic units?
Because volume measures space in three dimensions (length × width × depth).
Q3: When should I use cubic meters vs cubic feet?
Cubic meters are standard internationally; cubic feet are common in the United States.
Q4: How accurate is this calculator?
It uses exact mathematical formulas and precise unit conversion factors.
Q5: Can this formula be used for round objects?
No. Cylinders and spheres use different formulas.
