Cubic Meters Calculator

A cubic meters calculator converts a rectangular volume measured in feet into cubic meters. It multiplies the cubic feet by 0.0283168466, a factor that comes from cubing the foot's 0.3048 meter definition. For 100 cubic feet, the result is 2.832 cubic meters.

How to Calculate Cubic Meters

Volume in cubic feet (length × width × height) times 0.0283168466 gives the volume in cubic meters. That factor is the exact conversion, derived by cubing the foot's exact 0.3048 meter definition.

Example: 10 ft × 10 ft × 1 ft space

A 10 ft × 10 ft × 1 ft space: 1. Volume in cubic feet: 10 × 10 × 1 = 100 cu ft 2. Volume in cubic meters: 100 × 0.0283168466 = 2.832 cu m

What Is Cubic Meters?

A cubic meters calculator converts a rectangular volume measured in feet into cubic meters, useful when working with metric-specified materials or international volume specifications.

Cubic Meters: Pros and Cons

Pros

Uses the exact international conversion factor, not a rounded approximation
Gives both cubic meters and cubic feet, useful for comparing figures given in either unit
Works for any rectangular volume, from a small space to a large one

Cons

Only handles a rectangular (box-shaped) volume. A cylindrical or irregular shape needs a different formula
This site otherwise defaults to US customary units throughout. Use this calculator specifically when you need a metric volume figure
Doesn't convert linear or area units directly. See the Square Meters calculator for an area conversion

Frequently Asked Questions

How do I convert cubic feet to cubic meters?

Multiply by 0.0283168466, the exact conversion factor. 100 cu ft is 100 × 0.0283168466 = 2.832 cu m.

How many cubic feet are in a cubic meter?

About 35.315. It is the reciprocal of the cu ft to cu m factor (1 ÷ 0.0283168466 ≈ 35.315).

Why is the conversion factor 0.0283168466?

It comes from cubing the foot's exact definition of 0.3048 meters: 0.3048³ = 0.0283168466, with no rounding involved in the underlying relationship.

When would I need cubic meters instead of cubic feet?

Common cases include working with a metric-specified shipping container, comparing volumes against an international product specification, or following a project plan written in metric units.

Does this work for a non-rectangular volume?

No. This calculates a rectangular volume (length × width × height). A cylindrical volume needs π × radius² × height instead.
