• ✓US tbsp = 15 ml (practical); 14.787 ml (legal); 3 teaspoons in any system.
• ✓Australian tablespoon = 20 ml — 33% larger. Adjust when using Australian recipes.
• ✓For accurate cooking, weigh dry ingredients rather than measuring by tablespoon.

• ✗Using an Australian tablespoon (20 ml) for a US recipe (15 ml) — 33% overshoot.
• ✗Treating teaspoon and tablespoon as interchangeable — tablespoon is 3× larger.
• ✗Using a dinner spoon from the cutlery drawer as a tablespoon — they vary widely.

What is the Tablespoon?

The tablespoon equals exactly 15 milliliters (international culinary standard) or about 14.787 mL (US strict definition based on ½ fluid ounce). The tablespoon is a near-universal cooking measure for ingredients larger than a teaspoon but smaller than a cup — typical uses include oils, sauces, and condiments. The Australian tablespoon is uniquely 20 mL (4 teaspoons rather than 3), an oddity in international recipe interpretation. Standard recipes assume 1 tbsp = 15 mL globally except in Australia and the United States (where it is sometimes 14.787 mL but commonly rounded to 15 mL). The tablespoon relates to the teaspoon (3 tsp = 1 tbsp), the cup (16 tbsp = 1 cup), the fluid ounce (2 tbsp = 1 US fl oz), and the milliliter (1 tbsp = 15 mL conventional). Measuring spoons are calibrated to the local convention.

What is the Barrel?

The oil barrel equals exactly 42 US gallons (158.987 liters) and is the global benchmark unit for crude oil pricing and trading. The 42-gallon size dates to the 1860s Pennsylvania oil boom, when oil was shipped in repurposed wooden barrels of various sizes; the standard settled at 42 gallons as a practical industry compromise. Today, the oil barrel is virtually synonymous with crude oil — Brent crude and WTI prices are quoted per barrel ($/bbl), OPEC tracks production in barrels per day, and proven reserves are listed in billions of barrels. Despite metrication, the barrel persists in petroleum trading and journalism worldwide. It relates to the US gallon (1 bbl = 42 US gal), the cubic meter (1 bbl ≈ 0.159 m³), and the liter (1 bbl ≈ 159 L). Note that beer and wine barrels have different volumes.
