How Many Tablespoons in a Cup? The Ultimate Kitchen Conversion Guide
Introduction to Kitchen Measurement Conversions
Why Accurate Measurements Matter in Cooking
Whether you’re a beginner baker or a seasoned home chef, precise measurements can make or break a recipe.
One tablespoon too many—or too few—can throw off textures, flavors, and cooking times. That’s why understanding standard conversions like how many tablespoons in a cup is essential.
Metric vs. US Customary Units
The United States primarily uses the US Customary System, where volume is measured in cups, tablespoons (tbsp), and teaspoons.
Meanwhile, much of the world follows the Metric System with milliliters and grams. Knowing how to convert between these systems can save your recipe—especially when trying international dishes.

How Many Tbsp in 1/3 Cup Butter?
Measuring Butter by Tbsp and Cup
Butter is often packaged in sticks in the U.S., where 1 stick equals 1/2 cup or 8 tablespoons. To find how many tbsp in 1/3 cup butter, divide 16 tbsp (1 cup) by 3:
- 1/3 cup butter = 5 tbsp + 1 tsp
This is especially useful when measuring without a stick-marked wrapper.
Tips for Softened vs. Melted Butter
- Softened butter should be pressed firmly into a measuring cup for accuracy.
- Melted butter can be measured in a liquid measuring cup.
Always note whether your recipe calls for one or the other—it affects volume and consistency!
