🔬 Why Different Sugars Convert Differently

The Science of Sugar Density

Density: 220g/cup packed (0.93 g/ml) - See our detailed brown sugar guide

Crystal Structure Impact

  • 🔷
    Granulated: Uniform crystals pack efficiently
    Density: 200g/cup (0.85 g/ml)
  • 🟫
    Brown: Molasses coating = denser packing
    Density: 220g/cup packed (0.93 g/ml)
  • 💨
    Powdered: Ultra-fine = more air trapped
    Density: 120g/cup sifted (0.51 g/ml)

Recipe Scaling

When halving/doubling recipes, gram math is easier. Convert back to cups for measuring. For other ingredients, try our flour converter or butter converter.

Math: 300g ÷ 2 = 150g = ¾ cup

⚠️ Avoid These Conversion Mistakes

Mistake #1: Assuming All Sugars Are Equal

❌ Wrong: "100g of any sugar = ½ cup"

✅ Right: 100g granulated = ½ cup | 100g powdered = 0.83 cups | 100g brown = 0.45 cups

This mistake can make your frosting runny or cookies too dry!

Mistake #2: Not Considering Packing

❌ Wrong: Loosely scooping brown sugar for gram conversions

✅ Right: Pack brown sugar firmly - our conversions assume packed measurement

Loose vs packed can differ by 35%!

Mistake #3: Over-Rounding Numbers

❌ Wrong: "125g is about ½ cup" (loses 25g!)

✅ Right: 125g = ⅝ cup (0.625 cups) - use the exact measurement

Granulated: grams ÷ 200

Brown (packed): grams ÷ 220

Powdered (sifted): grams ÷ 120

Caster: grams ÷ 225

Examples:

100g granulated: 100 ÷ 200 = 0.5 cups

250g brown: 250 ÷ 220 = 1.14 cups

150g powdered: 150 ÷ 120 = 1.25 cups
