Measuring 450g of All-Purpose Flour in the Kitchen
Because 1 US Customary Cup (236.6 mL) of all-purpose flour weighs 120g when measured spooned & leveled, 450 Grams (450g) translates to 3.75 US cups (3 ¾ cups). By contrast, using the dip-and-sweep scooped measure (142g/cup — a 22g per-cup shift), 450g occupies 3 cups + 2 tbsp + 2 tsp (3.17 cups).
Without a kitchen scale, measure 3 ¾ cups (60 tablespoons total) using spooned & leveled technique. Fluff flour with a fork, spoon gently into the measuring cup until mounded, and sweep level with a straight knife. Never pack or tap the cup, which compresses flour up to 142g.

Frequently Asked Questions
How many cups is 450 grams of all-purpose flour? ▾
450 grams of all-purpose flour (spooned & leveled, 120g per US cup) equals 3 ¾ cups (3.75 US Customary Cups, 3.55 Metric 250 mL cups, or 60 tablespoons).
Why does 1 cup of all-purpose flour vary from 120g to 145g? ▾
Dipping the cup straight into the bag compacts the tiny particles, packing up to 25% more flour than gently spooning and leveling.
Can I swap all-purpose flour for bread flour by weight? ▾
Yes, substitute 100g of bread flour for 100g of AP flour, but note bread flour absorbs slightly more water due to higher protein.
