How Do You Convert Tablespoons to Milliliters?
Multiply the number of tablespoons by 14.7868 to get milliliters. The formula is: Milliliters = Tablespoons x 14.7868. To convert in the other direction, divide milliliters by 14.7868 to get tablespoons. This conversion uses the US customary tablespoon, which is the standard tablespoon measurement in American recipes and cookbooks.
Leah Novak at Rise & Shine Bakery in Pinewood Falls relies on this conversion whenever she scales recipes for large catering orders. Her signature lemon glaze calls for 3 tablespoons of fresh lemon juice. When she triples the recipe for Marco Ferreira's weekend brunch service at Marco's Kitchen, she needs 9 tablespoons. Converting to milliliters: 9 x 14.7868 = 133.08 mL, which she measures with a graduated cylinder for precision.
Common Tablespoon to Milliliter Conversions
The table below lists the tablespoon amounts that appear most often in recipes, along with their milliliter equivalents. These values use the US customary tablespoon (14.7868 mL).
| Tablespoons | Milliliters | Notes |
|---|---|---|
| 1/2 tbsp | 7.39 mL | 1.5 teaspoons |
| 1 tbsp | 14.79 mL | 3 teaspoons |
| 1.5 tbsp | 22.18 mL | Common sauce amount |
| 2 tbsp | 29.57 mL | 1 fluid ounce |
| 3 tbsp | 44.36 mL | Common recipe amount |
| 4 tbsp | 59.15 mL | 1/4 cup |
| 6 tbsp | 88.72 mL | 3/8 cup |
| 8 tbsp | 118.29 mL | 1/2 cup |
| 12 tbsp | 177.44 mL | 3/4 cup |
| 16 tbsp | 236.59 mL | 1 cup |
When Do You Need This Conversion?
Tablespoon to milliliter conversions come up in cooking, baking, medicine, and any situation where you need to bridge US and metric volume measurements. Here are the most common scenarios.
Scaling Recipes Up or Down
Marco Ferreira at Marco's Kitchen in Pinewood Falls often scales family recipes for restaurant service. His grandmother's pesto calls for 2 tablespoons of pine nuts and 4 tablespoons of olive oil. When he makes a batch ten times larger, the tablespoon math gets messy. Converting first makes it simpler: 4 tbsp x 14.7868 = 59.15 mL of olive oil per batch. Multiply by 10 to get 591.5 mL, which he measures directly with a graduated pitcher.
Following International Recipes
Leah Novak discovered a German strudel recipe that calls for 45 mL of melted butter. She needs to know how many tablespoons that is: 45 / 14.7868 = 3.04 tablespoons, so she uses 3 level tablespoons. When she adapted a Japanese milk bread recipe for Rise & Shine Bakery, the recipe listed 30 mL of honey. That converts to 2.03 tablespoons, close enough to use 2 tablespoons from her measuring set.
Medicine and Supplement Dosing
Many liquid medicines list doses in milliliters, but some older instructions still reference tablespoons. A dose of 15 mL equals 15 / 14.7868 = 1.01 US tablespoons. However, household tablespoons vary widely in actual volume. Medical professionals recommend always using a calibrated syringe or dosing cup rather than kitchen spoons for accurate dosing.
Baking with Precision
Baking demands accuracy, and small-volume ingredients like vanilla extract, lemon juice, and salt solutions are often measured in tablespoons. Leah's caramel recipe calls for exactly 1.5 tablespoons of sea salt solution. In milliliters, that is 1.5 x 14.7868 = 22.18 mL. She measures this with a small graduated cylinder because even half a milliliter too much salt can push a caramel from perfectly balanced to overwhelmingly salty.
