Understanding Volume Measurements
Volume measurements are used daily in cooking, beverage serving, fuel purchasing, and scientific experiments. The metric system uses milliliters and liters, while the US customary system uses fluid ounces, cups, quarts, and gallons. Kitchen conversions between these systems are among the most commonly searched unit conversions online.
For cooking, knowing that 1 tablespoon equals approximately 15 mL and 1 cup equals approximately 237 mL helps when adapting international recipes. For larger volumes, the US gallon (3.785 L) differs significantly from the imperial gallon (4.546 L), which can cause confusion in fuel economy comparisons.
