I know, I know—math is like that one friend who always shows up uninvited. But stick with me for two seconds. If 1 cup = 240 ml, then 1/3 cup = 80 ml. See? Easy. So 2/3 is just two of those 80 ml scoops: 80 + 80 = 160 ml.

You can even do this with your eyes closed. Or half-closed, if you’re tired. Just don’t spill.
What if you’re dealing with a recipe that calls for 2/3 of a liter? That’s a whole different beast. A liter is 1000 ml, so 2/3 of that is 666.67 ml. Creepy coincidence, right? But for baking, we’re usually stuck in cup-land, so stick to 160 ml.
Real talk: measuring cups vs. kitchen scale
Honestly, if you’re a frequent baker, get a kitchen scale. It’s a game-changer. Grams don’t lie, and they don’t fractions. But if you’re like me and still using grandma’s plastic cups, keep this 160 ml number tattooed in your brain.
A cheeky tip: Most standard shot glasses hold about 30 ml. So 2/3 cup is roughly 5 and 1/3 shot glasses. Is that helpful? Maybe not for baking, but it’s a fun party fact. You’re welcome.
