How It Works

How to Convert Rice Cups to Grams

Formula

Grams = Cups x Rice Density (g/cup)

Rice roughly triples in volume and weighs about 2.5x when cooked.

Rice Expansion

  • 1 cup dry rice produces about 2.5-3 cups cooked rice
  • 1 cup dry (185 g) yields roughly 460-555 g cooked

    • Worked Example

    Convert 1 cup of dry long grain white rice to grams.

    cups = 1rice_density = 185
    1. 01Long grain white rice density: 185 g per cup.
    2. 02Dry weight: 1 x 185 = 185 g.
    3. 03Approximate cooked weight: 185 x 2.5 = 462.5 g.
    4. 04Servings at 150 g each: 462.5 / 150 = 3.1 servings.
