How Many Tbsp in a 2/3 Cup? the Hidden 2 Teaspoon Mistake Ruining Your Bakes
Q1: What is the fastest way to measure a 2/3 cup without a 2/3 cup tool?
The easiest method is using your 1/3 cup tool twice. If your 1/3 cup tool is also missing, use your 1/2 cup tool once, then add 2 level tablespoons and 2 level teaspoons.
Q2: How many fluid ounces are in a 2/3 cup?
There are exactly 5.33 fluid ounces (fl oz) in a 2/3 US customary cup. In metric measurements, that equals roughly 158 milliliters.
Q3: Can I round 10 tablespoons and 2 teaspoons up to 11 tablespoons?
Rounding up to 11 tablespoons adds an extra teaspoon of volume. For hearty stews, chili, or marinades, that 3% variance is harmless. In layered sponge cakes, soufflés, and macarons, that extra tablespoon can cause batters to turn wet and heavy.
Q4: Does the conversion change when using British or Australian tablespoons?
Yes. An Australian tablespoon holds 20 milliliters (4 teaspoons) rather than the 14.8 milliliter US standard. An Imperial cup holds 284 milliliters, compared to the US cup at 237 milliliters. Always check the geographic origin of your recipe before calculating fractions.
