Cubic Feet to Liters Converter
Convert cubic feet (ft³) to liters (L)
Cubic Foot
Definition: A cubic foot (symbol: ft³ or cu ft) is a unit of volume in the imperial and US customary measurement systems. One cubic foot is the volume of a cube with sides of one foot (12 inches) in length. One cubic foot equals approximately 28.3168 liters or 7.48052 US gallons.
History/origin: The cubic foot is derived from the foot, which has been used as a unit of length since ancient times. The standardization of the foot to exactly 0.3048 meters in 1959 led to the cubic foot being defined as exactly (0.3048 m)³ = 0.028316846592 m³. The cubic foot has been widely used in construction, engineering, and cargo measurements throughout the English-speaking world.
Current use: The cubic foot is commonly used in the United States and United Kingdom for measuring volume in construction (concrete, lumber), cargo shipping (freight volume), refrigerators and freezers (storage capacity), air conditioning (airflow), and natural gas (consumption). It's particularly useful for measuring larger volumes where gallons or liters would result in large numbers. Converting cubic feet to liters is essential when working with international specifications or metric measurements.
Liter
Definition: The liter (symbol: L or l) is a unit of volume in the metric system. One liter is equal to 1,000 milliliters or 1 cubic decimeter (dm³). The liter is a derived unit accepted for use with the International System of Units (SI).
History/origin: The liter was introduced in France in 1795 as part of the new metric system. Originally defined as the volume of one kilogram of pure water at maximum density, it was later redefined in 1964 as exactly one cubic decimeter. The name "liter" comes from the French "litre," which was derived from an older French unit called the "litron."
Current use: The liter is the standard unit for liquid volume measurements worldwide, except in the United States. It's used extensively for beverages (soft drinks, water, juice), fuel (gasoline, diesel), and liquid products. Liters also measure dry goods in some contexts and are used in scientific measurements. Converting cubic feet to liters is essential when translating imperial volume specifications to metric measurements.

How to Convert Cubic Feet to Liters
Formula:
1 ft³ = 28.316846592 L (exact)
1 L = 0.0353147 ft³
L = ft³ × 28.316846592
Quick Mental Math:
Multiply ft³ by 28 to get approximate liters
For quick estimates, you can use 1 ft³ ≈ 28 L (within 1% accuracy)
Common Approximations:
1 ft³ ≈ 28 L (very close approximation)
2 ft³ ≈ 57 L
5 ft³ ≈ 142 L
10 ft³ ≈ 283 L
Useful Relationships:
1 cubic foot = 28.317 L = 7.481 gallons = 1,728 cubic inches
1 cubic yard = 27 ft³ = 764.555 L
1 cubic meter = 35.315 ft³ = 1,000 L
1 liter = 0.0353 ft³ = 61.024 cubic inches
Examples:
Convert 1 cubic foot to liters:
1 ft³ × 28.316846592 = 28.317 L
This is approximately 28 liters
