What Is a 1/3 tsp Measuring Spoon and Why Does It Matter?
A 1/3 tsp measuring spoon is a small kitchen tool designed to hold exactly one-third of a teaspoon. That is about 1.64 milliliters if you are working with a metric system. Most standard measuring spoon sets include sizes like 1 tablespoon, 1 teaspoon, 1/2 teaspoon, 1/4 teaspoon, and sometimes 1/3 teaspoon. Not all sets have it, which is why many cooks end up improvising — and that is where errors creep in.
The reason this matters so much comes down to precision. Baking, in particular, is a science. The ratio of flour to liquid to leavening determines whether your cookies spread perfectly or turn into flat puddles. Even in savory cooking, spices and seasonings need to be balanced. A 1/3 tsp of smoked paprika brings a smoky warmth. A 1/3 tsp of salt enhances flavor without making food salty. Get the amount wrong, and the dish suffers.
How Big Is 1/3 Teaspoon, Really?
To put it in perspective, a teaspoon is roughly the size of the tip of your finger from the crease to the tip. A 1/3 tsp is about one-third of that. It is a small mound, not a heaping spoonful. If you do not have a 1/3 tsp measuring spoon, you can approximate it by filling a 1/4 tsp spoon and adding just a tiny bit more. But that is a rough guess, and guessing is exactly what we want to avoid.
How to Measure 1/3 tsp Accurately Every Time
The good news is that measuring 1/3 tsp correctly is simple once you know the right method. Here is a step-by-step breakdown that works for both dry and liquid ingredients.
- Pick the right spoon. Use a dedicated 1/3 tsp measuring spoon if your set has one. Do not use a regular spoon from your drawer. Those are not standardized and can hold anywhere from 1.5 to 3 times the actual volume.
- Scoop the ingredient. Dip the spoon into your ingredient — whether it is salt, sugar, spices, or a liquid — and let it mound slightly above the rim.
- Level it off. Use the back of a knife or a flat spatula to sweep across the top. This removes the excess and gives you a perfectly level 1/3 tsp.
- Check your work. Hold the spoon at eye level to confirm it is level. This tiny habit takes two seconds and prevents over-measuring.
Measuring Dry vs. Liquid Ingredients
Dry ingredients like flour, cocoa powder, and spices should be spooned into the measuring spoon and then leveled. Packing them down or tapping the spoon can cause the ingredient to settle and give you more than 1/3 tsp. Liquid ingredients like vanilla extract or oil should be poured into the spoon until it sits right at the rim. The surface tension of the liquid will hold it in place if you pour slowly.
For very fine powders like cinnamon or cocoa, gently tap the spoon on the counter once or twice before leveling. This helps the powder settle without compressing it. If you are measuring something sticky like honey or molasses, lightly spray the spoon with cooking spray first. This makes it easier to release the full 1/3 tsp without leaving residue behind.
Conversions: What Else Equals 1/3 tsp?
One of the most useful skills in any kitchen is knowing how to convert measurements. When you do not have a 1/3 tsp measuring spoon, these equivalents can save the day.
- 1/3 tsp is approximately 1.64 ml in milliliters.
- 1/3 tsp is roughly 0.17 tablespoons (or about 1/6 of a tablespoon).
- 1/3 tsp equals about 1/8 teaspoon plus a small pinch for practical cooking purposes.
- In terms of cups, 1/3 tsp is a tiny fraction — far less than 1/4 cup, which is why we rely on teaspoon-sized tools for this amount.
Knowing these conversions helps when you are scaling recipes up or down. For instance, if a recipe calls for 1/3 tsp of salt and you want to double it, you will need 2/3 tsp, which is close to a half teaspoon plus a small pinch. If you are halving the recipe, you will need roughly 1/6 tsp, which is hard to measure without the right tool.

Best Measuring Spoon Sets That Include a 1/3 tsp
Not all measuring spoons are created equal. Some sets skip the 1/3 tsp size entirely, while others include it as a standard piece. Here is what to look for when choosing a set that works for you.
What to Look for in a Measuring Spoon Set
- Material: Stainless steel is durable and easy to clean. Plastic sets are lightweight and affordable. Avoid sets with painted markings that can wear off over time.
- Size range: Look for a set that includes 1/3 tsp. Many standard sets go from 1 tablespoon down to 1/4 teaspoon, skipping the 1/3. Seek out sets that fill this gap.
- Ergonomic handles: You want a comfortable grip, especially if you are measuring ingredients frequently while cooking.
- Leveling edge: Some premium sets include a built-in leveling rim on the spoon, which makes getting a perfect 1/3 tsp effortless.
Having the right tools in your kitchen makes a big difference. Once you have a reliable 1/3 tsp measuring spoon, keep it in a dedicated spot so it is always easy to find. If you want ideas on keeping your kitchen tools tidy, our article on how to organize measuring cups has practical tips you can use.
Quick Tip: The Finger Scoop Method
If you absolutely do not have a 1/3 tsp spoon, you can try the finger scoop method. Scoop a small amount of a dry ingredient with your fingertip — about the size of a small pea. This is a rough approximation of 1/3 tsp. It is not perfect, but it works in a pinch when you are seasoning a dish to taste rather than following a precise recipe.
Common Mistakes When Measuring 1/3 tsp
Even experienced cooks make measurement errors. Here are the most common mistakes and how to avoid them.
Mistake 1: Using a Regular Spoon
The biggest mistake is reaching for a dinner spoon or a coffee stirring spoon. A standard dinner spoon holds about 7 to 8 ml, which is roughly double a teaspoon. Using it to measure 1/3 tsp will give you way too much ingredient. Always use a proper measuring spoon.
Mistake 2: Eyeballing the Amount
It is tempting to just “eye it” when a recipe calls for a small amount. But eyeballing a 1/3 tsp is unreliable. Our eyes are not precise enough for such small volumes. Always use a tool designed for the job.
Mistake 3: Confusing 1/3 tsp with 1/4 tsp
This is a sneaky one. A 1/3 tsp is only slightly more than a 1/4 tsp, but that difference can matter a lot with strong flavors like salt, clove, or cayenne pepper. Make sure you are reaching for the right spoon, not just the closest one.
Mistake 4: Overfilling the Spoon
A heaping 1/3 tsp is not the same as a level 1/3 tsp. A heaping spoon can hold nearly twice the amount. Always level off your spoon for consistent results. This is especially important in baking, where precision directly affects the final product.
When Precision Matters Most
Not every recipe demands the same level of accuracy. Understanding when to be precise and when to be flexible will help you cook with confidence.
Baking: Precision Is Non-Negotiable
In baking, chemistry drives the process. Leavening agents like baking soda and baking powder react with acids and liquids to create rise. Too much or too little 1/3 tsp of baking powder can mean the difference between a fluffy muffin and a dense one. This is where a proper 1/3 tsp measuring spoon earns its keep.
Cooking and Seasoning: Flexibility Is Okay
When you are sautéing vegetables or simmering a soup, being off by a tiny bit on a spice measurement is less critical. You can taste as you go and adjust. But even here, having a 1/3 tsp measure helps you build layers of flavor more deliberately.

Expert Tips for Perfect Measurement Every Time
Here are some insider tips from experienced cooks and bakers that will take your measuring skills to the next level.
- Buy a kitchen scale. For the most accurate results, weigh your ingredients instead of measuring by volume. A digital kitchen scale takes the guesswork out of 1/3 tsp and all other measurements. Knowing how much 1/3 tsp of a specific ingredient weighs in grams gives you repeatable results every time.
- Keep a measuring cheat sheet on your fridge. Write down common conversions and tape them near your cooking station. It is a simple habit that saves time and prevents errors.
- Replace worn measuring spoons. Over time, the rims of cheap measuring spoons can chip or warp. A worn spoon will not hold an accurate 1/3 tsp. Inspect your tools regularly and replace them when needed.
- Measure over the bowl, not over the counter. If you spill a little 1/3 tsp of an expensive spice, that is money and flavor going to waste. Always measure over your mixing bowl or pot.
- Use the right spoon for the right job. A 1/3 tsp measuring spoon is designed for small, precise amounts. Using it for larger volumes or for stirring while measuring can lead to inaccurate results.
These small habits add up to big improvements in your cooking. The goal is not perfection in every single meal — it is consistency. When you know you are measuring correctly, you can focus on the fun parts of cooking, like experimenting with flavors and trying new recipes.
