How To Convert Teaspoon US to Cubic Centimeter
Formula: 1 Teaspoon US (tsp) = 4.92892159375 Cubic Centimeter (cm³).
Example: Convert 3 tsp to cm³.
3 × 4.92892159375 = 14.78676478125 cm³.
To do it by hand, multiply the number of US teaspoons by 4.92892159375. That gives you cubic centimeters, which are the same size as cc. If you need a quick estimate, you can use about 5 cm³ per tsp, then adjust for accuracy.
Quick Answer
1 Teaspoon US (tsp) = 4.92892159375 Cubic Centimeter (cm³)
- 0.5 tsp = 2.464460796875 cm³
- 2 tsp = 9.8578431875 cm³
- 10 tsp = 49.2892159375 cm³
Conversion Formula
cm³ = tsp × 4.92892159375
Recommended (standard definition): This uses the US teaspoon defined as 1/6 of a US fluid ounce, and 1 US fluid ounce = 29.5735295625 mL, with 1 mL = 1 cm³. So 1 tsp = 29.5735295625 ÷ 6 = 4.92892159375 cm³.
In simple words, you are changing a small cooking spoon measure (tsp) into a small volume unit (cm³ or cc). Since 1 cubic centimeter equals 1 milliliter, the result also tells you the volume in mL.
- Write your value in Teaspoon US (tsp).
- Multiply it by 4.92892159375.
- The answer is in Cubic Centimeter (cm³), also called cc.
Teaspoon
A teaspoon is a small unit of volume used mostly in cooking to measure ingredients. In the US system, its standard size is fixed for consistent measuring.
The teaspoon became common with recipe writing and household measuring sets. The symbol is tsp.
- Measuring salt, sugar, and spices in recipes
- Dosing small amounts of liquid medicine at home
- Mixing drinks, like adding syrup or flavorings
- Baking measurements for vanilla extract or baking powder
- Portioning small amounts of oils or sauces
Cubic Centimeter
A cubic centimeter is a metric unit of volume equal to the space of a cube that is 1 cm on each side. It is exactly the same as 1 milliliter, and it is often called cc.
This unit comes from the metric system and is widely used in science and engineering. The symbol is cm³.
- Measuring small liquid volumes in labs
- Engine size in vehicles, like 150 cc motorcycles
- Medical syringes and dosage measurements (cc or mL)
- Small container and packaging volume checks
- 3D printing and material volume calculations
Is this Conversion of Teaspoon US To Cubic Centimeter Accurate?
Yes. This conversion is based on fixed, widely accepted definitions: the US teaspoon equals 1/6 of a US fluid ounce, and the US fluid ounce is defined as 29.5735295625 milliliters. Since 1 milliliter equals 1 cubic centimeter, the factor 4.92892159375 cm³ per tsp is reliable for cooking, labeling, education, and general measurement work.

Real Life Examples
Here are practical situations where converting tsp to cm³ (cc) helps you measure more clearly.
- Recipe scaling: A sauce needs 2 tsp of vinegar. In metric tools, that is 2 × 4.92892159375 = 9.8578431875 cm³ (about 9.86 mL).
- Baking precision: A cookie recipe calls for 0.5 tsp vanilla extract. That equals 2.464460796875 cm³, useful if you measure with a small syringe or mL spoon.
- Medicine mixing: A caregiver adds 1 tsp of a liquid supplement to a drink. That is 4.92892159375 cm³, the same amount in a 5 mL style syringe (slightly under 5 mL).
- Nutrition tracking: You log 3 tsp of honey. In volume, that is 14.78676478125 cm³, helpful when comparing to metric labels.
- DIY liquids: You add 4 tsp of dye to paint. That equals 19.715686375 cm³, letting you repeat the mix using metric measuring cups.
- Coffee and tea: You use 6 tsp of syrup in a large drink. That is 29.5735295625 cm³, which is exactly 1 US fluid ounce in volume.
- Small lab or hobby projects: A hobbyist needs 12 tsp of water for a mixture. That equals 59.147059125 cm³, easy to measure as about 59.15 mL.
Quick Tips
- Exact method: multiply tsp by 4.92892159375 to get cm³.
- Remember: 1 cm³ = 1 mL = 1 cc, they match in size.
- Mental estimate: 1 tsp is about 5 cm³, then subtract a little for accuracy.
- If you double teaspoons, you double cm³, this conversion is linear.
- For halves and quarters, multiply first, then divide, for example 1 tsp ÷ 2 = 0.5 tsp.
- Write units every time, tsp for US teaspoon, cm³ for cubic centimeter.
