Cubic Feet to Cubic Meters Calculator
Convert cubic feet to cubic meters (ft³ to m³) for international shipping, HVAC specifications, and scientific volume measurements.
📐 What Is a Cubic Feet?
Cubic feet is the standard volume unit in the US for measuring room sizes, HVAC airflow rates (CFM), refrigerator capacity, storage unit sizes, and concrete orders. One cubic foot is the volume of a cube with sides measuring exactly 1 foot (30.48 cm).
📏 What Is a Cubic Meter?
The cubic meter is the SI standard for volume measurement, used internationally for shipping containers, water treatment, gas metering, and scientific research. Converting from ft³ to m³ is essential when translating US specifications for international markets.

🌍 Real-World Cubic Feet to Cubic Meters Examples
Refrigerator
20 ft³ = 0.566 m³ — typical large refrigerator capacity.
Moving Box
4.5 ft³ = 0.127 m³ — standard large moving box.
Room Volume
960 ft³ = 27.2 m³ — a 12×10×8 ft room.
Concrete Order
27 ft³ = 0.765 m³ = 1 cubic yard of concrete.
Natural Gas
1,000 ft³ (1 MCF) = 28.317 m³ — common gas billing unit.
HVAC Airflow
400 CFM = 11.33 m³/min — typical residential AC airflow.
🎯 Why Accurate Cubic Feet to Cubic Meters Conversion Matters
In the natural gas industry, volumes are often quoted in cubic feet (or MCF — thousand cubic feet) in the US but in cubic meters internationally. A billing error from incorrect conversion can cost thousands of dollars. Similarly, HVAC engineers must convert CFM specifications to m³/min when sourcing equipment from international manufacturers.
⚠️ Common Cubic Feet to Cubic Meters Conversion Mistakes
Using 3.28 Instead of 0.0283
3.28 converts linear meters to feet. For ft³→m³, multiply by 0.0283168.
Confusing ft³ with yd³
1 yd³ = 27 ft³. Make sure you know which unit you're starting with.
CFM is Not Volume
CFM is a flow rate (volume/time). To get total volume, multiply CFM by time in minutes.
Direction Confusion
ft³→m³: multiply by 0.0283 (number gets smaller). m³→ft³: multiply by 35.31 (number gets bigger).
💡 Tips for Faster Cubic Feet to Cubic Meters Conversion
Divide by 35
For a quick ft³→m³ estimate, divide by 35. Example: 700 ft³ ÷ 35 ≈ 20 m³ (exact: 19.82).
Container Reference
1,172 ft³ ≈ 33 m³ (20ft container). 2,390 ft³ ≈ 68 m³ (40ft container).
Key Value
1 ft³ = 28.3 liters. Useful for aquariums and tanks.
Water Weight
1 ft³ of water weighs 62.4 lbs (28.3 kg).
