How Volume Conversions Are Calculated

Our online volume converter operates using a single base unit: the liter (L). Regardless of the unit you input—be it a US gallon, a cubic meter, or a milliliter—the calculator first translates it into liters. From there, it converts the liters into your desired unit, employing precise conversion factors. This two-step approach guarantees accurate and consistent results for all liquid, solid, and container volume conversions.

Examples: 1 US cup × 236.588 = 236.588 mL; 2 ft³ × 28.3168 = 56.6336 L; 0.5 m³ × 1000 = 500 L.
