About Tablespoons
A tablespoon (tbsp) is a US customary cooking measurement equal to 3 teaspoons or 1/2 fluid ounce - approximately 14.787 mL. It is the standard 'large spoon' measurement in hundreds of millions of American recipes - used for butter portions, oil, sugar, sauce, and condiment quantities. Outside cooking, tablespoons appear in DIY instructions, garden fertilizer dosages, and cleaning product formulations. A typical soup spoon holds roughly one tablespoon. The tablespoon is the practical bridge between the tiny teaspoon and the larger cup in everyday kitchen measurement.
About Gallons
A US gallon (gal) = 4 quarts = 128 fl oz ≈ 3.785 L. Gasoline, milk, water, paint, and pesticides are sold by the gallon in the US. About 20% smaller than the UK imperial gallon (4.546 L) - a critical difference when comparing fuel economy across the Atlantic. 1 US gal = 3.785 L = 4 qt = 128 fl oz.
