Tablespoon (US) (Tbsp)
The US tablespoon, symbolized as Tbsp, equals 3 teaspoons or approximately 14.7868 milliliters. Originally based on the dining table spoon, it became standardized in the United States for cooking and nutrition. Tablespoons are widely used in recipes, food labeling, and the pharmaceutical industry. Like teaspoons, they enable consistent measurements in both home kitchens and professional culinary settings. The simplicity of linking teaspoons to tablespoons ensures practical, error-free conversions.
Gallon (US)
The US gallon, symbol gal, equals 4 quarts, 8 pints, or 128 fluid ounces (~3.785 liters). Its origins trace to English wine and ale measures but were standardized in the US in the 19th century. Gallons are used for beverages, fuel, and large-volume recipes. While metric liters are the dominant unit of measurement in most countries, gallons remain widely used in the United States for everyday and industrial liquid measurements.
