  • 8 oz = 227g = 1.82 cups
  • 16 oz (1 lb) = 454g = 3.63 cups

Measurement method matters! Scooped flour can be 20% heavier than spooned & leveled flour. For best results, use the method specified in your recipe.

⚠️ Your Measuring Method Can Ruin Your Recipe!

Same "1 Cup" - Different Results

✅ Spooned & Leveled 125g
❌ Scooped & Packed 150g
⚠️ Scooped (no pack) 140g
💨 Pre-sifted 119g

What This Means For Your Baking

25g extra per cup =
  • • Dense, heavy cakes
  • • Dry, crumbly cookies
  • • Bread that won't rise properly
Correct measurement =
  • • Light, fluffy texture
  • • Perfect moisture
  • • Consistent results

Quick Answer: 1 cup flour = 125g

(when measured correctly with spoon & level method)

The Right Way to Measure Flour (Visual Guide)

1️⃣

Fluff First

Stir flour in container to aerate

↻ Breaks up compaction
2️⃣

Spoon Gently

Spoon flour into measuring cup

🥄 Don't tap or shake!
3️⃣

Overfill Slightly

Heap flour above cup rim

⬆️ Creates level surface
4️⃣

Level Off

Use knife back to level

➖ Perfect 125g!

📏 This method works for all dry ingredients. See our baking powder guide and cocoa powder converter.

✅ Why Spooned is Standard

  • • Most recipes assume this method
  • • Gives consistent results
  • • Matches nutrition labels

❌ Why Scooping Fails

  • • Compresses flour particles
  • • Varies by person (10-30% more)
  • • Causes recipe failures

Recipe Troubleshooting: Was It The Flour?

Common Problems From Wrong Flour Measurement:

Too Much Flour (Scooped)

  • 🍪
    Cookies: Dry, crumbly, won't spread
  • 🎂
    Cakes: Dense, heavy, dry crumb
  • 🥖
    Bread: Tough, doesn't rise well

Too Little Flour (Under-measured)

  • 🍪
    Cookies: Spread too thin, crispy edges
  • 🎂
    Cakes: Sunken center, gummy texture
  • 🥖
    Bread: Won't hold shape, sticky

🎯 Perfect your technique with recipes that need precise measurements: French Macarons (requires exact ratios) or Classic Pound Cake (1:1:1:1 ratio).

Frequently Asked Questions

Why does my recipe fail even when I follow the measurements?

The most common reason is measuring method! Even if a recipe says "1 cup flour," results vary:

  • Author scooped = 150g (but wrote "1 cup")
  • You spooned = 125g (following best practice)
  • Result = 25g less flour = recipe failure

Solution: Look for recipes that specify weight (grams) or measuring method.

How do professional bakers measure flour?

Professionals ALWAYS weigh ingredients:

  • Digital scale accuracy: ±1 gram
  • Cup measurement variance: ±25 grams
  • Consistency: 100% vs 80%

My grandma's recipes just say "1 cup flour" - which method did she use?

Older recipes (pre-1990s) typically assumed the scoop method:

  • 1950s-1970s recipes: Usually scooped (140-150g)
  • Hand-written recipes: Often scooped
  • Modern recipes: Usually spooned (125g)

Tip: If an old recipe seems dry, try using 10-15% less flour.

Does altitude affect flour measurement?

Yes! At high altitude (above 3,000 feet):

  • Flour is drier = weighs less per cup
  • You may need 1-2 tbsp more flour
  • Measuring by weight eliminates this variable

Baking at altitude? Use our high altitude calculator.

Can I convert old recipes from cups to grams?

Yes, but consider the era and source:

  • Pre-1990s: Use 140-150g per cup
  • Modern blog recipes: Use 125g per cup
  • Professional cookbooks: Often specify method
  • Family recipes: Test and adjust

Start with the standard 125g and adjust if needed.
