Why Rice Weight Changes
When you cook rice, the grains absorb water, which causes them to increase significantly in weight and volume. This process is called starch gelatinization. The amount of expansion depends on the variety of rice, the cooking method, and the amount of water used.

Cooking Tips & FAQs
Should I track rice cooked or uncooked?
It's always most accurate to weigh rice uncooked. This removes variables like how much water was absorbed or lost during steaming. Most nutritional labels provide information for the uncooked product.
How much water should I use?
Most white rice varieties use a 1:2 ratio (one part rice to two parts water). Brown rice often requires more water (1:2.5) and a longer cooking time to soften the outer bran layer.
Does rinsing rice change the weight?
Rinsing removes excess surface starch and can add a tiny amount of water weight, but it's negligible for calculation purposes. Rinsing is recommended for fluffier rice that doesn't clump.

These calculations are estimates based on standard cooking methods (boiling/steaming). Variations in water-to-rice ratios, altitude, and cooking equipment can affect the final weight of cooked rice.
