Cubic Feet to Liters Calculator

How to convert cubic feet to liters

One cubic foot holds 28.3168 liters. The factor follows from 1 ft³ = 0.0283168 m³ and 1 m³ = 1,000 L. Multiply cubic feet by 28.3168 to get liters.

Worked examples

Common uses

• European fridge, freezer, and oven capacities
• Aquarium and fish-tank volume
• Coolers, water bottles, and beverage containers
• Industrial and chemical container volume

Where this conversion comes up

Liters is the metric equivalent of gallons and the standard for any non-US fluid spec. Use it for international product comparisons and SI-unit work.

• European refrigerators and freezers — quoted in liters.
• Aquariums and lab equipment — liters is the universal unit.
• International water storage tanks.
• Engineering specs that follow the SI standard.

Common mistakes to avoid

• Confusing liters with milliliters. 1 liter = 1,000 ml. If you are calculating from a cm³ measurement, that equals milliliters — divide by 1,000 to get liters.
• Treating liters as a weight. Liters measure volume; kilograms measure mass. They are equal only for water (1 L of water ≈ 1 kg).
• Mixing US and metric for tank specs. Some US-made tanks list both gallons and liters. Read the spec carefully — they don't convert exactly the same way as cubic feet.

Expert tips

1. Multiply cubic feet by 28.3168 to get liters. Or, more memorably: ft³ × 28.3 gets you very close.
2. Liters is the universal unit for European appliances.Refrigerators, freezers, and washing machines outside the US are quoted in liters. See refrigerator and freezer calculators.
3. For lab and pharma work, liters is the standard. Aquariums, fish tanks, and chemistry equipment are spec'd in liters globally. 1 ft³ = 28.32 L is the working approximation.
4. For cooking, milliliters and liters dominate outside the US. A recipe in ml or L converts cleanly: 1 L = 0.0353 ft³.
