Beverages & juices
Sugary drinks and juices are significantly denser than plain water due to dissolved solids. Converting 'cups' to grams is the best way to accurately track sugar intake or mix precise cocktails and punches.

FAQ
Is 1 cup of juice 240g? Not exactly. Because of the sugar content, 1 cup of juice usually weighs between 250g and 260g. Our calculator accounts for this density.
Primer
These category tables convert volume to mass using ingredient-specific densities. Use weight for precision; volume varies with packing, cut, and temperature.
Methodology
- Density references are summarized from U.S. government sources (USDA FoodData Central, USDA FNDDS) and lab-standard data when available.
- Conversions keep higher-precision intermediates and round to practical kitchen values.
- Default volume is the US cup unless a page explicitly uses metric or UK standards.
Unit standards
- Mass: grams (g).
- Volume: mL, US cup, tbsp, tsp.
- Assumed temperature: room temperature unless stated otherwise.
Examples and edge cases
- Juice vs concentrate differ in solids and density (USDA FDC).
- Carbonation changes fill and foam volume (USDA FDC).
- Milk-based drinks are heavier than water-based (USDA FDC).
