   Multiply by 0.000031

   The conversion factor from tsp to bbl is 0.000031. Multiply your value by this number.
3. 3
   Read the result in barrels

   The result is your value in barrels (bbl).

Multiply the value in teaspoons by 0.000031. For the reverse direction, multiply by 32,256.01.

• ✓1 tsp = 5 ml (practical); 4.929 ml (US legal).
• ✓3 tsp = 1 tbsp universally.
• ✓Use a proper measuring spoon — household teaspoons vary 3–8 ml.

• ✗Using a regular cutlery teaspoon for medication — can over- or under-dose by 30–60%.
• ✗Mixing tsp and tbsp — 3× difference.
• ✗Assuming "a pinch" or "a dash" is reproducible — it varies 0.1 to 0.5 ml.

What is the Teaspoon?

The teaspoon equals exactly 5 milliliters (international culinary standard) or about 4.929 mL (US strict definition based on 1/3 of a tablespoon). The teaspoon is the smallest standard cooking measure, used worldwide for spices, baking soda, vanilla extract, salt, and small ingredient quantities. A flat (level) teaspoon is the recipe convention; rounded or heaping teaspoons are inconsistent and avoided in serious cooking. The teaspoon is also a medical unit: many liquid medications are dosed in teaspoons (5 mL standard). The teaspoon relates to the tablespoon (1 tbsp = 3 tsp), the cup (48 tsp = 1 cup), the milliliter (1 tsp = 5 mL conventional), and the fluid ounce (6 tsp = 1 fl oz). Standardized 5-mL measuring spoons are available globally to avoid the variability of household teaspoons (which range from 2 to 7 mL).

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.
