When a recipe says tsp or tbsp, using the wrong one can change the amount of an ingredient and affect the final result. Tsp means teaspoon, while tbsp means tablespoon. A tablespoon is usually three times the volume of a teaspoon, but exact measurements can vary by country.
This simple difference often causes confusion because recipes use these abbreviations instead of writing the full words. A small typo or a quick glance can also turn “1 tsp” into “1 tbsp,” which is a much larger amount.
Knowing the difference between tsp and tbsp is useful when cooking, baking, following a recipe, measuring medicine or reading food instructions. It is especially important when an ingredient is strong, such as salt, baking soda, spices or extracts.
In this guide, you will learn what tsp and tbsp mean, how their measurements compare, where the abbreviations come from, how different countries use them, and how to avoid common measurement mistakes.
Tsp or Tbsp: Quick Answer
Tsp stands for teaspoon.
Tbsp stands for tablespoon.
The basic relationship is:
- 1 tbsp = 3 tsp in common US and metric cooking measurements.
- 1 tsp = about 5 mL.
- 1 US tbsp = about 15 mL.
- 3 tsp = about 1 tbsp.
Simple examples
If a recipe asks for:
- 1 tsp of salt, use one teaspoon.
- 1 tbsp of olive oil, use one tablespoon.
- 2 tsp of sugar, use two teaspoons.
- 1 tbsp of lemon juice, use one tablespoon.
The easiest way to remember the difference is that a tablespoon is larger than a teaspoon.
However, do not assume that every country uses exactly the same tablespoon size. Australian recipes, for example, commonly use a 20 mL tablespoon, which is different from the 15 mL tablespoon used in many US and metric recipes.
What Does Tsp or Tbsp Mean?
What does tsp mean?
Tsp is the standard cooking abbreviation for teaspoon.
A teaspoon is a small unit commonly used for measuring ingredients such as:
- Salt
- Sugar
- Spices
- Vanilla extract
- Baking powder
- Baking soda
- Sauces
In many modern recipes, one teaspoon is approximately 5 mL.
For example:
Add 1 tsp of vanilla extract.
This means:
Add 1 teaspoon of vanilla extract.
What does tbsp mean?
Tbsp is commonly used as an abbreviation for tablespoon.
A tablespoon is larger than a teaspoon and is often used for ingredients needed in greater amounts.
Examples include:
- Cooking oil
- Vinegar
- Honey
- Milk
- Soy sauce
- Lemon juice
- Peanut butter
In many US and metric recipes:
1 tbsp = 3 tsp
So:
2 tbsp = 6 tsp
and:
½ tbsp = 1½ tsp
Why do recipes use abbreviations?
Recipes use abbreviations because they save space and make ingredient lists easier to scan.
For example:
2 tbsp olive oil
1 tsp salt
½ tsp black pepper
is shorter and easier to read than:
2 tablespoons olive oil
1 teaspoon salt
½ teaspoon black pepper
The Origin of Tsp and Tbsp
The words teaspoon and tablespoon developed from everyday serving and measuring practices.
A teaspoon originally referred to a small spoon used for tea. A tablespoon referred to a larger spoon associated with serving food at the table.
Over time, these words became useful as standardized cooking measurements.
The abbreviations tsp and tbsp are modern shorthand forms used in recipes, cookbooks, food labels and cooking instructions.
The important point is that the physical size of ordinary household spoons is not always the same as a standardized measuring spoon. A spoon from your kitchen drawer may hold more or less than an actual measuring teaspoon or tablespoon.
That is why measuring spoons are more reliable when accuracy matters.
British English vs American English
The terms teaspoon and tablespoon are used in both British and American English. The main issue is not the vocabulary. It is the measurement system used by the recipe.
| Term | British English | American English | Example |
| Teaspoon | Commonly about 5 mL in modern recipes | About 4.93 mL | 1 tsp salt |
| Tablespoon | Commonly 15 mL in modern metric recipes | About 14.79 mL | 1 tbsp oil |
| Common ratio | 1 tbsp = 3 tsp | 1 tbsp = 3 tsp | 3 tsp = 1 tbsp |
| Abbreviation | tsp / tbsp | tsp / tbsp | 2 tbsp sugar |
Modern UK recipes often use metric measurements, while US recipes commonly use customary measurements.
The small difference between a US teaspoon and a 5 mL metric teaspoon usually does not matter for many everyday recipes. But it can matter when a recipe requires high precision.
A special case: Australia
Australia commonly uses a 20 mL tablespoon.
That means:
1 Australian tbsp = 4 Australian tsp
This is an important exception to the common 3-to-1 relationship.
If you are using an Australian recipe, check the recipe’s measurement system before converting tablespoons to teaspoons.
Which Version Should You Use?
There is no single abbreviation that is better for every country. The correct choice depends on the recipe and its measurement system.
United States
For US recipes:
- tsp = teaspoon
- tbsp = tablespoon
- 1 tbsp = 3 tsp
- 1 US tbsp ≈ 14.8 mL
Use standard measuring spoons when possible.
United Kingdom
UK recipes commonly use metric measurements.
A tablespoon is commonly treated as 15 mL, and a teaspoon as 5 mL in modern recipes.
Always follow the recipe’s stated measurement system if one is provided.
Canada
Canadian recipes may use a mix of metric and other measurement conventions. Check if the recipe gives measurements in milliliters, teaspoons or tablespoons.
Australia
Be especially careful with Australian recipes.
An Australian tablespoon is commonly 20 mL, while a teaspoon is 5 mL.
Therefore:
1 Australian tbsp = 4 tsp
International writing
For an international audience, writing the measurement in milliliters can reduce confusion.
For example:
1 tbsp (15 mL) olive oil
This is clearer than relying only on the abbreviation.
Academic writing
Academic or technical writing should favor clarity over casual shorthand.
If measurements are important, define the measurement system and use consistent units.
Business writing
Food businesses, recipe publishers and product instructions should make measurements easy to understand.
For international readers, including both the abbreviation and milliliter value can be useful.
Common Mistakes
Mistake 1: Confusing tsp with tbsp
Incorrect:
Add 1 tbsp of salt when the recipe calls for 1 tsp.
Correct:
Add 1 tsp of salt.
Explanation: A tablespoon is larger than a teaspoon. Using a tablespoon instead of a teaspoon can add roughly three times as much in common US and metric measurements.
Memory tip: Think T in tbsp as the larger tablespoon.
Mistake 2: Assuming a kitchen spoon is a measuring spoon
Incorrect:
Use any small spoon for 1 tsp.
Correct:
Use a standardized measuring teaspoon.
Explanation: Everyday spoons can have different capacities.
Memory tip: When accuracy matters, use measuring spoons.
Mistake 3: Assuming every tablespoon equals 15 mL
Incorrect:
Every tablespoon everywhere equals 15 mL.
Correct:
Many recipes use a 15 mL tablespoon, but some countries use different tablespoon sizes.
Explanation: Australian tablespoons are commonly 20 mL.
Memory tip: Check the recipe’s country or measurement system.
Mistake 4: Reading tsp as tbsp
Incorrect:
The recipe says 1 tsp, so I used 1 tbsp.
Correct:
Follow the abbreviation exactly as written.
Explanation: The difference can significantly affect the amount of an ingredient.
Memory tip: tsp = teaspoon = smaller measurement.
Everyday Examples
Emails
A recipe shared by email might say:
Add 2 tbsp of olive oil and 1 tsp of salt.
The abbreviations keep the ingredient list short and easy to scan.
Business Writing
Food companies may write:
Mix 1 tbsp of sauce with 2 tsp of vinegar.
For international customers, adding milliliter values can make the instructions clearer.
News Headlines
A food article may use words rather than abbreviations:
How to Measure a Teaspoon and Tablespoon Correctly
News and general-interest writing often spells out terms when the audience may not know the abbreviations.
Blogs
Food blogs commonly use both forms:
1 tbsp honey
2 tsp cinnamon
The abbreviations are especially useful in ingredient lists.
Social Media
Short-form recipes often use:
1 tbsp butter
½ tsp pepper
This format saves space and is easy to read on a phone.
Academic Writing
A scientific or educational text may prefer:
5 mL
instead of relying only on “1 tsp,” especially when precise measurement is important.
Daily Conversation
Someone might say:
Add a teaspoon of sugar.
In conversation, people usually say teaspoon or tablespoon rather than the abbreviations.
Google Trends & Modern Usage
People searching for tsp or tbsp are usually trying to solve a practical measurement problem. They may be following a recipe, converting measurements, checking an abbreviation or wondering if tsp and tbsp mean the same thing.
Searches such as these are common forms of the same question:
- What does tsp mean?
- What does tbsp mean?
- Is tbsp bigger than tsp?
- How many tsp are in a tbsp?
- How much is 1 tbsp in tsp?
- Is a teaspoon the same as a tablespoon?
- How many mL is a tablespoon?

However, international recipes can create confusion because measurement conventions differ. This is why recipes aimed at a global audience often include milliliter values alongside teaspoons and tablespoons.
Exact search-volume or Google Trends figures should not be assumed without checking current Google Trends data. The usage discussion here is based on common recipe and measurement conventions rather than invented statistics.
