Summary: Original ingredient weight is 240g and scaled weight is 600g.
Summary: Scaling a recipe from 4 to 10 servings multiplies all ingredients by 2.5×. Your 2 cup of All-Purpose Flour (spooned & leveled) (120 g/cup per King Arthur Baking / USDA Weight Chart) scales to 5 cup, which weighs 600 grams (21.16 oz) or 1182.9 mL.

Formula & Mathematical Methodology: Portion Multiplier & Bulk Density Mass-Volume Conversion

Scale Multiplier = Target ServingsOriginal Servings,   Weight (g) = Scaled Cups × Density (g/cup)
Scale = TargetServings / OriginalServings; Grams = ScaledCups × Density(g/cup)
  • Density(g/cup): Mass in grams of 1 US standard cup (236.588 mL) of the chosen ingredient

Rounding: Grams and mL round to 1 decimal place; cups and ounces round to 2 decimal places.

Worked Example: Scale 2 Cups of All-Purpose Flour from 4 Servings to 10 Servings

A 4-serving recipe calls for 2 cups of all-purpose flour (120 g/cup). Scale it to 10 servings and convert to grams.

  1. Scale multiplier = 10 ÷ 4 = 2.5×.
  2. Scaled volume = 2 cups × 2.5 = 5.0 US cups (1,182.9 mL).
  3. Scaled weight = 5.0 cups × 120 g/cup = 600.0 grams (21.16 oz).
Result: 5.0 US cups = 600.0 grams (21.16 oz) at a 2.5× recipe multiplier.

Frequently Asked Questions

Why does 1 cup of flour weigh 120g while 1 cup of water weighs 236.6g?

A cup measures volume (space), not mass. Sifted flour contains air pockets and has a bulk density of ~0.51 g/mL, whereas liquid water has a density of 1.00 g/mL.

How to Use the Cooking Conversions & Recipe Scaling Calculator: Practical Guide & Visual Analysis

Convert imprecise volume measurements (cups and tablespoons) into accurate kitchen-scale gram weights for flour, sugar, butter, oats, milk, honey, rice, and oil while scaling recipe yields. Whether you are researching recipe scaler, cups to grams calculator, flour cups to grams, baking conversion calculator, portion multiplier, this interactive tool helps you scale recipe quantities up or down by serving count and convert culinary volume units (cups, tbsp, tsp, mL) to exact kitchen scale weights (grams and ounces) using real ingredient densities.

Interpreting the 3 Custom Visual Graphs & Key Outputs

As you adjust Original Recipe Yield (Servings), Target Servings Needed, Ingredient (USDA Density Profile), Original Ingredient Quantity, the calculator immediately computes Scaled Weight in Grams (g) & Ounces (oz), Scaled Volume in US Cups & Tablespoons, Scaled Volume in Milliliters (mL), Recipe Multiplier (×) and updates all three domain-specific SVG charts in real time. Instead of relying on a single static figure, you can inspect the primary domain diagram, component breakdown, and multi-point trajectory curve to see how changing your inputs shifts the final result. Use the Compare (up to 3 scenarios) button to evaluate side-by-side variations before making a decision.

Real-World Benchmark & Planning Tips (Global (US Customary Cup = 236.59 mL & Metric Grams))

In our benchmark scenario (Scale 2 Cups of All-Purpose Flour from 4 Servings to 10 Servings), 5.0 US cups = 600.0 grams (21.16 oz) at a 2.5× recipe multiplier. Keep in mind that flour density assumes the standard spooned-and-leveled method (120 g/cup) rather than scooped-and-packed.
