Formula & Calculation Methodology
All volume measurements convert through the standard metric liter (L = 1 dm³ = 0.001 m³). 1 US liquid gallon is legally defined as exactly 231 cubic inches (approx 3.785411784 liters).
Worked Example
Converting 10 US gallons of water to liters
Converting 1 cubic yard of mulch/concrete to cubic feet
Frequently Asked Questions
What is the difference between a US gallon and an Imperial gallon?↓
A US liquid gallon is approximately 3.785 liters (231 cubic inches), while an Imperial (UK) gallon is 4.54609 liters (originally defined as the volume of 10 pounds of distilled water at 62°F).
How many liters are in one cubic meter?↓
Exactly 1,000 liters make up one cubic meter (1 m³ = 1,000 L).
How many cubic feet are in a cubic yard?↓
Since 1 yard = 3 feet, a cubic yard contains 3 × 3 × 3 = 27 cubic feet.
What is a limitation when converting liquid volume to mass (weight)?↓
Volume conversion strictly calculates space; translating volume to mass requires multiplying by density (e.g., 1 L of water is 1 kg, but 1 L of gasoline is only ~0.74 kg).
