Understanding Liters in the Metric System
The liter is the international standard unit for volume measurements.
What is a Liter?
A liter (L) is a metric unit of volume equal to 1 cubic decimeter (dm³) or 1,000 cubic centimeters (cm³).
1 liter = 1 dm³ = 1,000 cm³ = 1,000 mL
Liters are used worldwide in science, engineering, and everyday life in most countries.

Conversion Formula Explained
The Standard Formula
Liters (L) = Cubic Feet (ft³) × 28.3168
This is the internationally recognized conversion factor.
Where does 28.3168 come from?
1 ft³ equals 0.0283168 m³, and 1 m³ equals 1,000 liters. Combine them:
1 foot = 0.3048 meters
1 ft³ = (0.3048 m)³ = 0.0283168 m³
1 m³ = 1,000 liters
1 ft³ = 0.0283168 × 1,000 = 28.3168 L
Step-by-step example
Let's convert 15 cubic feet to liters:
- Start with the formula: L = ft³ × 28.3168
- Substitute the value: L = 15 × 28.3168
- Calculate: L = 424.752
- Result: 15 ft³ = 424.75 liters
Reverse conversion
Cubic Feet (ft³) = Liters (L) ÷ 28.3168
Or multiply by 0.0353147 (same result).
Practical scientific example
A lab needs a tank for 500 liters. Convert to ft³ for a US supplier:
500 ÷ 28.3168 = 17.66 ft³
A 3ft × 3ft × 2ft tank (18 ft³) provides ~509.7 liters, leaving a little headroom.
Quick mental math
For quick estimates, use 30 instead of 28.3168 (about a 6% overestimate). For precise scientific or engineering work, use the exact factor.

Frequently Asked Questions
Answers to common questions about ft³ to liters conversions.
1How many liters are in a cubic foot?
How many liters are in a cubic foot?
There are 28.3168 liters in one cubic foot. This is the standard conversion factor used internationally. To convert cubic feet to liters, multiply by 28.3168.
2What is the formula to convert cubic feet to liters?
What is the formula to convert cubic feet to liters?
The formula is: Liters = Cubic Feet × 28.3168. For example, 10 cubic feet = 10 × 28.3168 = 283.168 liters. This conversion is based on the relationship between feet and meters in the metric system.
3How do you convert cubic feet to liters for water tanks?
How do you convert cubic feet to liters for water tanks?
Calculate the tank volume in cubic feet (Length × Width × Height in feet), then multiply by 28.3168 to get liters. For example, a 2ft × 2ft × 2ft tank = 8 ft³ = 226.5 liters.
4What's the difference between liters and cubic meters?
What's the difference between liters and cubic meters?
1 cubic meter = 1,000 liters. Liters are used for smaller volumes (beverages, containers), while cubic meters are used for larger volumes (rooms, shipping). 1 cubic foot = 28.3168 liters = 0.0283168 cubic meters.
5How many liters is a 100 cubic foot tank?
How many liters is a 100 cubic foot tank?
A 100 cubic foot tank holds 2,831.68 liters (100 × 28.3168 = 2,831.68 L). This is approximately 2.83 cubic meters or 748 US gallons.
6Why do scientists use liters instead of gallons?
Why do scientists use liters instead of gallons?
Scientists use liters because the metric system (SI) is the international standard, it’s decimal-based (1 L = 1,000 mL), and it integrates cleanly with other metric units. Gallons are mainly used for everyday purposes in the US and a few other places.
7How accurate is the 28.3168 conversion factor?
How accurate is the 28.3168 conversion factor?
28.3168 is accurate for most practical uses. The full factor is 28.316846592 liters per cubic foot; using 28.3168 is a rounded value with a very small error for typical calculations. For high-precision work, use the full factor.
8Can I use this conversion for gases as well as liquids?
Can I use this conversion for gases as well as liquids?
Yes—this converts volume, regardless of what fills the space. For gases, remember volume changes with temperature and pressure. For solids, volume does not equal weight without density.
