Convert cubic meter to cubic foot.

Convert cubic meter (m³) to cubic foot (ft³). This is a fixed-ratio conversion — multiply the input by the factor below.

Formula

ft³ = m³ × 35.3147

Reference values

Things to watch for

• US and UK gallons are different. 1 US gal = 3.785 L; 1 UK (imperial) gal = 4.546 L. Recipes from the UK will not work with US cups.
• Volume scales as the cube of length: doubling a container's dimensions multiplies volume by 8, not 2.
• For viscous or compressible fluids, volume changes with temperature and pressure. Specify conditions for precise work.

What is a cubic meter?

One cubic meter equals exactly 1,000 liters. Building volumes, shipping container capacity, water-utility billing, and natural-gas measurement.

How to picture a m³

If the unit feels abstract, comparing it to known objects often helps.

• 1 m³ — about the size of a large refrigerator.
• 2.5 m³ — roughly the volume of a typical bathtub filled twice over.
• 33 m³ — about a 20-foot shipping container.

How to convert cubic meter to ft3

To convert a value from cubic meter (m³) to ft3 (ft3), apply the conversion factor shown in the formula above. The calculation is the same whether you do it by hand, in a spreadsheet, or with the live converter on this page.

Steps:

1. Take your input value in m³.
2. Apply the formula ft³ = m³ × 35.3147.
3. The result is your value in ft3.

For repeated calculations, save the formula in a spreadsheet or use the live converter at the top of this page — it handles the math automatically and displays the result as you type.

Frequently asked questions

How do I convert m³ to ft3?

Apply the formula m³ → ft3 shown above, or just type your value into the converter at the top of this page. The result updates instantly.

Which is bigger, m³ or ft3?

This depends on the conversion ratio in the formula. If the factor multiplied by your value gives a larger number, then ft3 is the smaller unit (so it takes more of them to express the same quantity). If the result is smaller, then ft3 is the larger unit.

When would I use m³ versus ft3?

Both units measure volume, so the choice depends on context. Cubic meter is typically used for cooking, beverages, fuel, and industrial fluid handling; ft3 similarly. Most professional fields standardize on one or the other based on regional conventions or technical tradition.

How precise is this m³ to ft3 conversion?

The conversion factor shown is the internationally defined exact value (or the best-published approximation if the relationship is irrational, like degrees-to-radians). The live converter on this page uses double-precision floating-point math, accurate to about 15 significant digits — far beyond any practical engineering need.

Is the conversion ratio exact, or an approximation?

Most unit conversions between SI metric units, and between SI and US customary units, have been formally defined as exact values since the 1959 international yard-pound agreement and subsequent SI redefinitions. Exceptions are unit pairs that involve irrational numbers (radians, e.g.) or empirical conversions (like food calories, which depend on temperature). When in doubt, consult the formula at the top of this page.
