Cups ↔ grams, spoons ↔ milliliters — by ingredient density, as you type.

Using All-purpose flour ≈ 0.529 g/mL

How to use it

  1. Type the amount — the result appears as you type. There is no button to press.
  2. Pick the units: volume (ml, L, tsp, tbsp, fl oz, cup) and weight (g, kg, oz, lb) can be combined freely.
  3. When converting between volume and weight (like cups to grams), pick the ingredient — its density does the work. Same-kind conversions (cups to tablespoons) ignore the ingredient, so it is greyed out.
  4. Results in US volume units also show the nearest common fraction (≈ 1/2 cup). Copy the result with one click, or reset everything with Clear.

Example

Input

1 cup all-purpose flour → grams

Result

125.155 g
Using all-purpose flour ≈ 0.529 g/mL

1 US cup is exactly 236.588 ml, and all-purpose flour has an average density of about 0.53 g/mL — so one cup weighs roughly 125 g. The same cup of granulated sugar (0.845 g/mL) weighs about 200 g.

Rules, limits and known issues

  • Ingredient densities are average cooking references — they vary with brand, packing and humidity. Treat results as close approximations, not lab-grade measurements.
  • Units follow US customary definitions: 1 cup = 236.588 ml = 16 tbsp = 48 tsp, and 1 lb = 453.592 g. Metric cups (250 ml) are not used.
  • Only unit conversion is offered — scaling a recipe from 2 to 4 servings, temperature conversion and nutrition are separate problems and not part of this tool.
  • A negative or invalid amount shows an error instead of a misleading result; an empty amount simply clears the result.
  • Numbers are formatted by your browser (Intl): decimal digits, digit grouping and Arabic-Indic digits follow your page language.
  • Nothing is uploaded, stored or written to the URL: no history, no share link carrying your numbers, no remote call.
