Convert US tablespoons (Tbsp) to milliliters (ml) and vice versa. Accurate and easy-to-use for cooking, baking, and medication dosages.

What is a Tablespoons to Milliliters Converter?

A Tablespoons to Milliliters (Tbsp to ml) Converter is a tool used to convert volume measurements from US tablespoons to milliliters. This is particularly useful in cooking, baking, medicine dosage, and any other situation where precise liquid measurements are required and need to be translated between these two common units.

Understanding this conversion is important because recipes and dosage instructions can vary in the units they use. This calculator ensures accuracy when you need to switch between tablespoons and milliliters.

Tablespoons to Milliliters Conversion Formulas

The conversion is based on the standard US tablespoon measurement:

  • US Tablespoons to Milliliters: Milliliters = Tablespoons × 14.7867648
  • Milliliters to US Tablespoons: Tablespoons = Milliliters / 14.7867648

Where:

  • Tbsp stands for US tablespoon(s)
  • ml stands for milliliter(s)

Note: This calculator specifically uses the US tablespoon. Other tablespoon measures exist (e.g., UK, Australian) which have different milliliter equivalents.

How to Convert Tablespoons to Milliliters: Example

Let's say you have a recipe that calls for 3 US tablespoons of an ingredient.

  1. Identify the value in tablespoons: 3 Tbsp
  2. Apply the conversion formula (Tbsp to ml): Milliliters = 3 × 14.7867648
  3. Calculate: Milliliters ≈ 44.36 ml

So, 3 US tablespoons is approximately 44.36 milliliters.

Conversely, if you have 50 ml of liquid:

  1. Identify the value in milliliters: 50 ml
  2. Apply the conversion formula (ml to Tbsp): Tablespoons = 50 / 14.7867648
  3. Calculate: Tablespoons ≈ 3.38 Tbsp

So, 50 milliliters is approximately 3.38 US tablespoons.

Common Applications

This conversion is frequently used in:

  • Cooking and Baking: Many recipes, especially older or American ones, use tablespoons. Converting to milliliters allows for use with metric measuring tools or for international recipes.
  • Medicine: Liquid medication dosages are often prescribed in milliliters for accuracy, but some over-the-counter medications might still refer to tablespoon measures (though this is less common for precision).
  • Chemistry and Lab Work: Small volume measurements are common, and converting between units can be necessary.
  • Bartending: Drink recipes can use either unit.
  • Crafts and DIY Projects: Mixing paints, resins, or other liquids often requires precise volume conversions.
