Tablespoons to Teaspoons (tbsp to tsp) Converter

Convert tablespoons to teaspoons using standard volume factors.

Kitchen Conversion Basics

In cooking and baking, especially in the US, measurements are based on a standard hierarchy. Memorizing just three simple rules will allow you to convert almost any recipe.

1 Tablespoon = 3 Teaspoons
1 Fluid Ounce = 2 Tablespoons
1 Cup = 16 Tablespoons

From these three rules, all other conversions can be found:

  • 1 Cup = 16 Tablespoons = **48 Teaspoons**
  • 1 Cup = 8 Fluid Ounces = **16 Tablespoons**
  • 1/2 Cup = 8 Tablespoons = **24 Teaspoons**
  • 1/4 Cup = 4 Tablespoons = **12 Teaspoons**

Cooking Conversion Chart (US)

For convenience, here is a chart for the most common measurements you'll find in recipes.

Measurement Cups Fluid Ounces Tablespoons Teaspoons
1 Cup 1 8 fl oz 16 tbsp 48 tsp
1/2 Cup 1/2 4 fl oz 8 tbsp 24 tsp
1/4 Cup 1/4 2 fl oz 4 tbsp 12 tsp
1 Tablespoon 1/16 0.5 fl oz 1 tbsp 3 tsp
1 Teaspoon 1/48 ~0.167 fl oz 1/3 tbsp 1 tsp

Frequently Asked Questions (FAQ)

How many teaspoons are in a tablespoon?

There are **3 teaspoons (tsp)** in 1 tablespoon (tbsp). This is the most fundamental conversion in US kitchen measurements.

How many tablespoons are in a cup?

There are **16 tablespoons (tbsp)** in 1 US Customary Cup.

Is a UK tablespoon the same as a US tablespoon?

No, they are different, which can be confusing.
• **US Tablespoon:** 14.79 mL (defined as 1/2 US fl oz)
• **UK/Imperial & Metric Tablespoon:** 15 mL (this is the modern standard in the UK, Canada, and Australia).
For most recipes, this small difference is not critical, but for precise baking, it can matter.
