• ✓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 Quart?

The US quart equals exactly one quarter of a US gallon (0.946352946 liters) and is a common kitchen and motor-oil volume in the United States. The word 'quart' derives from the Latin 'quartus' meaning fourth. Milk and motor oil are commonly sold in quart containers (a quart of motor oil is 32 fl oz), and large recipes call for quart-sized stockpots. The US quart is distinct from the slightly larger UK imperial quart (1.137 L). It relates to the gallon (4 qt = 1 gal), the pint (2 pt = 1 qt), the cup (4 cups = 1 qt), the fluid ounce (32 fl oz = 1 qt), and the liter (1 US qt ≈ 0.946 L). The quart is a useful intermediate volume between the cup (small recipe measurements) and the gallon (bulk liquids).
