Okay, let’s get dorky for a second. 2/3 cup is also:
• 10 tablespoons plus 2 teaspoons.
• Or 5.33 fluid ounces.
• Or 158 milliliters.
Fun fact: 2/3 cup is exactly the volume of a standard baseball. Yep. A baseball fits perfectly into 2/3 of a cup. Try that at your next ballgame. You’ll get weird looks. Do it anyway.
Why Does This Even Matter?
Because recipes are liars. They say “2/3 cup” like it’s simple. But then you’re hunting for that one measuring cup that’s always missing. You know the one. It’s behind the mixing bowls, covered in dried pancake batter.
And what if you only have a 1/3 cup? Easy: use it twice. That’s literally 2/3. No magic. No fractions on a napkin. Just pour, pour, done.
