How It Works
This converter uses the cubic meter as its base unit. Every volume unit has a known factor relative to one cubic meter, and the tool multiplies by the source factor then divides by the target factor.
Results are calculated with BigNumber precision so even conversions between very small units (milliliters) and very large units (cubic kilometers) remain accurate.
Example
Convert 5 US gallons to liters: 5 × 3.785412 = 18.927 L. The factor 3.785412 represents the number of liters in one US liquid gallon, derived from the definition of the gallon as exactly 231 cubic inches.
Frequently Asked Questions
How many liters are in a gallon?
One US liquid gallon equals approximately 3.78541 liters. One UK (imperial) gallon is larger at approximately 4.54609 liters. Always check which gallon standard is being used.
What is the difference between a fluid ounce and an ounce?
A fluid ounce measures volume (liquid capacity), while an ounce measures mass (weight). One US fluid ounce is approximately 29.5735 mL of water, but the actual mass depends on the liquid’s density.
How many cups are in a liter?
One liter is approximately 4.227 US cups or 4.0 metric cups. The metric cup (250 mL) is commonly used in recipes outside the United States.
