How Cubic foot Relates to Liter
What is Cubic foot?
Cubic foot (ft³) is a unit of volume measurement. 1 cubic foot is equal to 28.3168466 liter.
The Liter Explained
Liter (L) is a unit of volume measurement. 1 liter is equal to 0.0353147 cubic foot.
Volume Measurement Systems
Volume units are particularly confusing because the US and UK gallons differ (US gallon = 3.785 L, UK gallon = 4.546 L), as do their pints, cups, and fluid ounces. Cooking, fuel economy, beverage production, and pharmaceutical compounding all require precise volume conversions. Laboratory work uses milliliters and liters while US recipes specify cups, tablespoons, and fluid ounces.

Solved Examples: Cubic Feet to Liters
Question 1: An aquarium is 4 cubic feet. How many liters of water does it hold?
Solution:
Liters = cubic feet × 28.3168
= 4 × 28.3168
= 113.27 liters
Answer: A 4 ft³ aquarium holds 113.3 liters (about 30 gallons).
Question 2: A refrigerator is advertised as 22 cubic feet. Express capacity in liters.
Solution:
Liters = 22 × 28.3168
= 622.97 liters
Answer: 22 ft³ = 623 liters of interior capacity.
Question 3: An HVAC system moves 400 cubic feet of air per minute (CFM). How many liters per minute?
Solution:
Liters/min = 400 × 28.3168
= 11,326.7 L/min
Answer: 400 CFM = 11,327 liters per minute.

Aquarium Sizing: Cubic Feet to Liters and Gallons
Aquarium hobbyists need to convert between cubic feet (tank dimensions), liters (for metric fish-keeping guides), and gallons (for US equipment ratings). A standard 55-gallon aquarium is about 7.35 ft³ or 208 liters. To estimate: measure the tank in inches (L×W×H), divide by 1,728 to get cubic feet, then multiply by 28.317 for liters. Water weighs 8.34 lbs per gallon, so a 55-gallon tank holds about 459 lbs of water — check your floor strength!
HVAC Airflow: CFM to Liters per Second
HVAC systems rate airflow in cubic feet per minute (CFM). To convert to liters per second (L/s), the international standard: CFM × 28.3168 ÷ 60 = L/s (or simply multiply CFM × 0.4719). A typical bathroom fan (50 CFM) moves 23.6 L/s. A central air handler at 1,200 CFM moves 566 L/s. International building codes specify ventilation requirements in L/s per person or per m² of floor area.
Refrigerator Capacity: What Cubic Feet Actually Means
Refrigerator "cubic feet" ratings measure usable interior volume. A typical 20 ft³ fridge has 567 liters of storage space. However, about 20-30% is occupied by shelves, drawers, and ice makers, leaving 400-450 liters of actual usable space. European fridges are rated in liters directly, making comparison easier. When comparing: US ft³ × 28.3 = liters, but expect 70-80% to be truly usable.
Key Takeaways
- Multiply cubic feet by 28.3168 to get liters.
- 1 cubic foot = 28.317 L = 7.48 US gallons.
- Aquariums: 1 ft³ ≈ 7.5 gallons ≈ 28 liters of water.
- Refrigerators: 20 ft³ ≈ 567 liters total capacity.
- HVAC: 1 CFM = 0.4719 liters per second (L/s).
- A cubic foot of water weighs about 62.4 lbs (28.3 kg).
