Measuring 16 oz (1 lb) 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, 16 Ounces (453.6g) translates to 3.78 US cups (3 ¾ cups + 1 ½ tsp). By contrast, using the dip-and-sweep scooped measure (142g/cup — a 22g per-cup shift), 16 oz occupies 3 cups + 3 tbsp + ¼ tsp (3.19 cups).

Without a kitchen scale, measure 3 ¾ cups + 1 ½ tsp (60.48 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 16 ounces (16 oz) of all-purpose flour? ▾

16 ounces (453.6 grams) of all-purpose flour (spooned & leveled, 120g per US cup) equals 3 ¾ cups + 1 ½ tsp (3.78 US Customary Cups, 3.58 Metric 250 mL cups, or 60.48 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.
