Legumes & pulses
Dry, cooked, and canned legumes differ widely in volume and mass. Pick the correct state before converting.

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
- Flour: sifted vs. packed can shift grams per cup.
- Brown sugar: packed vs. loose changes mass at the same volume.
- Butter: softened vs. cold affects density and volume fill.
- Chopped vs. whole pieces change void space in a cup.
