Cubic Feet to Cubic Meters Calculator
Cubic feet and cubic meters are both used to describe the volume of rooms, enclosures, and vaults. When blueprints arrive in imperial units but the specification calls for metric, this calculator makes the conversion fast and accurate.
Enter a volume in cubic feet and get the result in cubic meters and liters. The output updates as you type, handling any positive number including decimals.
Conversion Formula
m³ = ft³ × 0.0283168
1 cubic foot = 0.0283168 cubic meters
Since one cubic meter equals 1,000 liters, multiply the cubic meter result by 1,000 for liters. For example, 100 cubic feet equals 2.832 cubic meters, or 2,831.68 liters.
Frequently Asked Questions
How many cubic meters are in one cubic foot?
One cubic foot equals approximately 0.0283168 cubic meters. This factor comes from the fact that one foot is 0.3048 meters, and cubing that value (0.3048 cubed) gives 0.0283168.
When do contractors use cubic feet to cubic meters conversion?
This conversion is common on international projects, when submitting metric-based documentation, or when sizing electrical rooms and vaults where specifications are provided in cubic meters. It also comes up when comparing HVAC airflow volumes across imperial and metric standards.
How do I convert cubic feet to liters?
Multiply cubic feet by 28.3168 to get liters, since one cubic meter equals 1,000 liters and one cubic foot is 0.0283168 cubic meters. This calculator provides both cubic meters and liters in the output.
