How many cups is 100 grams of white rice?

One hundred grams of dry long-grain white rice equals approximately 0.54 US cups (about half a cup). Using a metric cup (250 ml) it is roughly 0.52 cups.

How many cups is 200 grams of rice?

Two hundred grams of dry long-grain white rice is approximately 1.08 US cups — just over one cup. For brown rice at 190 g/cup, 200 g is about 1.05 US cups.

How does cooked rice compare to dry rice by volume?

Rice roughly doubles or triples in volume and weight when cooked because it absorbs water. One cup of dry white rice yields about 3 cups of cooked rice. The cooked density used here is approximately 195 g per US cup for white rice.

What is the difference between a US cup and a metric cup?

A US cup holds 240 ml, while a metric (Australian/Canadian) cup holds 250 ml. The difference is about 4%, which matters when scaling large quantities.

Why are the grams-per-cup values different for each rice variety?

Each variety has different grain shape, length, and moisture content, which affects how densely the grains pack into a measuring cup. Shorter or rounder grains like arborio pack more densely, while slender long-grain varieties like basmati pack less densely.

Is this tool accurate for sushi rice?
