how many grams of flour in a cup

One standard cup of all-purpose flour weighs approximately 120-125 grams.

This value is widely used in baking conversions, though slight variations exist based on flour type and measurement method.

Why Flour Weights Vary

Flour density changes with how it's scooped—spooned loosely or packed tightly into a cup.
Experts like King Arthur Baking recommend the "spoon and level" method for consistency, yielding about 120 grams per cup.

Sifting or aerating flour first can reduce the weight to around 110-115 grams by adding air.

Flour Type Breakdown

Different flours have unique densities due to grind and protein content.

Flour Type| Grams per US Cup (≈240ml)
---|---
All-Purpose| 120-125 g 15
Bread Flour| 127 g 1
Cake Flour| 113 g 1
Whole Wheat| 120 g 1
Rye Flour| 129 g 1

Quick Measurement Tips

• Weigh for precision : Use a kitchen scale to avoid volume pitfalls—baking pros swear by grams over cups.

• Formula: Grams = cups × 125 (for all-purpose). Example: 2 cups = 250g.

• US cup = 240ml; adjust for metric (250ml) by adding ~4-5g.

Pro Baker Insights

Bakers debate this endlessly on forums: Some stick to 128g from hands-on tests, others 120g for sifted flour.

In 2026 trends, apps like baking converters default to 125g amid rising home baking post-2025 surges.

TL;DR : Use 125g for a safe all-purpose bet—your cookies will thank you.
