About Volume Conversion
Volume is the measurement of three-dimensional space occupied by a substance or contained in a container. It is essential in cooking, science, engineering, and everyday life.
The metric system uses liters (L) and milliliters (mL) as the primary units. The US system uses gallons (gal), quarts (qt), pints (pt), cups, fluid ounces (fl oz), tablespoons (tbsp), and teaspoons (tsp).
Key relationships: 1 gallon = 4 quarts = 8 pints = 16 cups = 128 fluid ounces. 1 liter ≈ 0.264 US gallons. For cooking, 1 cup = 16 tablespoons = 48 teaspoons.
