'00' Flour — Measurement Converter
A US cup of '00' flour (also called doppio zero flour, pizza flour) weighs 116 g. Working back the other way, 100 g is about 7/8 cup and 250 g is about 2 1/8 cups. Use the calculator for any amount in between.
💡 Tip: The "00" on Italian flour refers to how finely it's milled, not its protein level. Its silky texture is prized for pizza and fresh pasta.

What the '00' actually means
The "00" (doppio zero) on Italian flour refers to how finely it's milled, not its protein content — it's the softest, most talc-like grade. It weighs about 116 g per cup, a little less than all-purpose flour because the fine particles trap more air. There are different protein levels within 00: low-protein 00 is sold for tender fresh pasta, while a higher-protein "00 pizza" flour is built to handle the long fermentation and blistering heat of a Neapolitan oven.
You can swap it for all-purpose in a pinch, but the silky bite that makes 00 prized for pizza and pasta won't be quite the same.

There are 16 tablespoons in a cup, so one tablespoon of '00' flour weighs roughly 7.25 g — and a teaspoon 2.42 g.
How '00' flour compares with other flours & starches
116 g per cup places '00' flour in the middle of its category — lighter than all-purpose flour (120 g) and heavier than cake flour (114 g).
That gap matters when you substitute by volume: use a cup of all-purpose flour where the recipe wanted '00' flour and you have added about 4 g extra — 3% more than intended. Weighing instead of scooping removes the problem.
