Convert dry ounces, grams or pounds to cups and cups to dry ounces for common ingredients, with metric cups, tbsp, tsp, mL and custom grams per cup.
Assumptions Assumptions
- “Ounce” here means ounce by weight (oz), not fluid ounce (fl oz).
- Density values are approximate grams per US cup; expect variation by brand, grind, humidity, and measuring method.
- Level cups assumed; brown sugar listed as packed when specified.
- Unit standards: US customary cup = 236.5882365 mL; US legal cup = 240 mL; metric cup = 250 mL; Imperial cup = 284.130625 mL; US tbsp = 14.78676478125 mL; US tsp = 4.92892159375 mL; 1 oz = 28.349523125 g.
- An Imperial cup is supported at 284.130625 mL. Spoon outputs are always US tablespoons and teaspoons; Imperial spoons are not used.
When to Use This Calculator
- Converting a recipe that lists ingredients by weight to cups (or vice versa).
- Standardizing recipes for kitchens that measure by cups instead of a scale.
- Quick ingredient swaps where densities differ (e.g., flour vs. sugar).
Input Definitions
- Ingredient — selects a density (grams per US cup), or choose “Custom” to enter your own.
- Dry Weight — enter oz, g, or lb.
- Volume — choose US customary, US legal, metric or Imperial cups; US tbsp, US tsp, mL or L. US spoon sizes stay fixed regardless of cup selection.
- Conversion — cups(US) = (oz × 28.349523125) ÷ (grams per US cup). For cups → oz: oz = (cups × grams per US cup) ÷ 28.349523125.

Dry Ounce to Cup Formula
The following formula converts dry ounces to cups using grams and the ingredient’s density in grams per US cup.
cups = (oz × 28.349523125) / (g per US cup)
- 1 oz = 28.349523125 g
- US cup = 236.588 mL
- Metric cup = 250 mL
- Example densities (g/US cup): all-purpose flour ≈ 120; granulated sugar ≈ 200; butter ≈ 227.

How do you convert dry ounces to cups? Multiply ounces by 28.349523125 to get grams, then divide by the ingredient’s grams per US cup (cups = oz × 28.349523125 ÷ g/US cup).
How do you convert cups to dry ounces? Multiply cups by the ingredient’s grams per US cup, then divide by 28.349523125 (oz = cups × g/US cup ÷ 28.349523125).
Example Problem
Convert 12 oz of all-purpose flour to US cups.
Use the formula: cups = (oz × 28.349523125) ÷ (grams per US cup).
cups = 12 × 28.349523125 ÷ 120 ≈ 2.835 US cups
