Assumptions used

What this answer assumes

Best for pure cubic unit conversion. Use shape/material calculators when volume depends on dimensions, density, waste, yield or supplier rules.

  • The converter treats all inputs as cubic volume, not floor area, length, mass, density or material order quantity.
  • Cubic feet and cubic yards use the international foot, where 1 ft = 0.3048 m exactly.
  • One cubic yard equals 27 cubic feet, or 0.764554857984 cubic metres.
  • This page does not replace material-specific calculators for concrete, pool volume, excavation, mulch, gravel, cylinder geometry or supplier ordering rules.

Master’s Tip

How to use the result well

Master’s Tip: keep pure cubic conversion separate from material estimating. A cubic-yard concrete order, pool fill, excavation spoil pile or gravel load may need waste, density, shape or supplier rules after the unit conversion.

Formula

Convert the source unit to litres first, then convert litres to the target cubic unit. One cubic foot = 28.316846592 L. One cubic metre = 1000 L. One cubic yard = 764.554857984 L.

Worked example

For 100 cubic feet to cubic metres: 100 ft³ x 28.316846592 L = 2,831.6846592 L, and 2,831.6846592 L ÷ 1000 = 2.8316846592 m³.

Professional note

Master’s Tip: keep pure cubic conversion separate from material estimating. A cubic-yard concrete order, pool fill, excavation spoil pile or gravel load may need waste, density, shape or supplier rules after the unit conversion.

Regional and unit assumptions

Standard or basis: exact international-foot cubic conversion and SI litre/cubic-metre scaling. This is a cubic-volume worksheet, not a material-ordering, freight-rating, density or engineering compliance tool.

Assumptions and limitations

Methodology & Accuracy

How this calculator is checked

CalculationTime pages are built around visible arithmetic: the formula, assumptions, worked example and practical limitations are shown so the result can be checked rather than simply trusted.

Formula used

Convert the source unit to litres first, then convert litres to the target cubic unit. One cubic foot = 28.316846592 L. One cubic metre = 1000 L. One cubic yard = 764.554857984 L.

Standard or basis

Standard or basis: exact international-foot cubic conversion and SI litre/cubic-metre scaling. This is a cubic-volume worksheet, not a material-ordering, freight-rating, density or engineering compliance tool.

Where a calculator follows a named legal, trade or industry standard, that standard is cited visibly. Otherwise the page uses transparent general arithmetic and states its limits.

Questions

Why use one Volume Converter instead of separate cubic-foot pages?

Cubic feet, cubic metres and cubic yards are one small cubic-volume family. One survivor page lets users change direction without spreading crawl value across duplicate one-direction URLs.

Which cubic units are covered?

This survivor page covers cubic feet, cubic metres and cubic yards.

How many cubic feet are in one cubic yard?

One cubic yard contains exactly 27 cubic feet.

How many cubic metres are in one cubic foot?

One cubic foot is exactly 0.028316846592 cubic metres when using the international foot.

When should I use a material-specific calculator instead?

Use a concrete, pool, excavation, mulch, gravel or cylinder calculator when the job also depends on shape, waste, density, compaction, yield, bag count or supplier rounding.

Calculation note

Cubic-volume conversion is length conversion carried into three dimensions. Cubic feet, cubic metres and cubic yards measure space, so the conversion must preserve the volume basis rather than treating it like a line or flat area.

Cubic volume uses three dimensions

A cubic foot changes length, width and height together. Because one foot is exactly 0.3048 metres, one cubic foot is 0.3048 cubed cubic metres.

Cubic yards are common in material ordering

Cubic yards are useful in concrete, gravel, mulch, excavation and landscaping conversations, but the order quantity usually needs material-specific allowances after the pure conversion.

Cubic metres bridge metric engineering and trade notes

Metric drawings and engineering records commonly use cubic metres. Keeping cubic feet, cubic yards and cubic metres on one page makes the conversion reversible and auditable.
