Baking Conversion Calculator

By Muhammad Abdullah Rauf · Founder, EverydayTools.proUpdated 2026-06-27

How do I convert cups to grams for baking?

Baking conversion uses **ingredient-specific density** (grams per US cup), not a single universal factor.

**Formula:**

Grams = Cups × grams_per_cup (for that ingredient)

Tbsp → grams: (tbsp ÷ 16) × grams_per_cup

**Example — 1 cup flour:**

1 × 120 = **120 g**

**Example — 1 cup sugar:**

1 × 200 = **200 g**

Cup-to-gram density conversion

Volume converted through ingredient-specific grams-per-cup, with tbsp via 16 tbsp per cup.

Formula

grams = amount × (g_per_cup for ingredient); tbsp path: (tbsp/16) × g_per_cup

Assumptions

  • US customary cups (240 mL nominal).
  • Standard home-baking densities (flour 120, sugar 200, brown sugar 220, butter 227, cocoa 85, oats 90 g/cup).
  • Spoon-and-level flour measurement.

Limitations

  • Packed vs sifted flour can shift weight ±10%.
  • Does not replace a kitchen scale for precision baking.
  • Brand and humidity affect real-world cup weights.

How to use Baking Conversion Calculator

  1. Choose ingredient

    Select flour, sugar, brown sugar, butter, cocoa, or oats — density changes per ingredient.

  2. Enter amount

    Type the quantity in cups, tablespoons, or grams.

  3. Pick from and to units

    Convert cups ↔ grams or tbsp ↔ grams.

  4. Read converted amount

    Use the result in your recipe or scale with Recipe Scaler.

  5. Weigh on a scale

    For best accuracy, confirm critical amounts on a digital scale.

Best practices

Weigh when scaling

Match ingredient type

Common mistakes to avoid

Using one grams-per-cup for all ingredients

Flour and sugar have **different** densities — pick the right ingredient.

Scooping flour from the bag

Spoon flour into the cup and level — scooping packs extra grams.

Ignoring recipe scaler

Convert to grams **after** scaling servings with Recipe Scaler.

Frequently Asked Questions

How many grams in 1 cup of flour?

About **120 g** for spoon-and-level all-purpose flour. Scooping from the bag can add 10–20 g.

How many grams in 1 cup of sugar?

**200 g** for granulated sugar. Brown sugar (packed) is about **220 g/cup**.

How do I convert tablespoons to grams?

Divide tbsp by 16 to get cups, then multiply by the ingredient's grams-per-cup. 1 tbsp flour ≈ 7.5 g.

Why does ingredient matter for cups to grams?

Density varies — a cup of flour weighs less than a cup of sugar because sugar packs more mass per volume.

Baking conversion vs Recipe Scaler?

Recipe Scaler changes amounts for more/fewer servings; Baking Conversion changes units (cups ↔ grams).

Is 1 cup always 240 mL?

US recipes use ~240 mL cups; this tool uses standard US **weight** equivalents per ingredient, not liquid volume alone.

How many grams is ½ cup butter?

About **113–114 g** (227 g per cup × 0.5).

Should I use grams for baking?

Yes — professional and European recipes use weight because it is more repeatable than volume.

Cocoa powder cups to grams?

1 cup cocoa ≈ **85 g** in this tool's standard density table.

Do oats convert the same as flour?

No — rolled oats are about **90 g/cup** vs flour at **120 g/cup**.
