100 grams rice
to cups.

Rice must be identified as dry or cooked, and grain type matters. This page answers the common dry long-grain case rather than borrowing a cooked-rice number.

Short answer100 g of uncooked long-grain dry rice is about 0.51 US cup, commonly rounded to about ½ cup.

King Arthur Baking lists ½ cup of long-grain dry rice as 99 g. The 100 g result is calculated from that cited reference.

Dry and cooked rice are not interchangeable

The headline answer is for uncooked, long-grain dry rice. Cooking changes water content and volume, so a cooked-rice conversion needs its own specific source and should not reuse the dry value.

Rice varieties such as basmati, jasmine, sushi, brown, and instant rice can also differ. Use a package instruction when it identifies the exact product and cup convention.

The source calculation

King Arthur Baking lists ½ cup of long-grain dry rice as 99 g. Dividing 100 g by that reference gives approximately 0.51 US cup. The practical rounded measure is about ½ cup, not an exact universal constant.

A level cup and a kitchen scale are more reproducible than compressing grains into a cup. Keep the rice dry/uncooked qualifier beside the result.

Do not repurpose FDA serving amounts

FDA reference amounts list 45 g dry and 140 g prepared for plain grains such as rice. Those are labelling reference amounts, not cup-weight data, so they should not be converted into cups without a separate sourced volume measurement.

Questions readers ask

Is 100 g rice dry or cooked?

This page's answer is for uncooked long-grain dry rice. Cooked rice requires a separate source because water uptake changes the result.

Is 100 g dry rice exactly ½ cup?

Using King Arthur's 99 g per ½-cup reference, it is about 0.51 US cup, so ½ cup is a practical rounded measure.

Does jasmine rice use the same value?

Not necessarily. Grain variety, brand, moisture, and packing can change volume, so use a product-specific instruction when available.

Can I use a rice-cooker cup?

Do not assume it is a US cup. Rice-cooker cups can follow a different convention; check the appliance or recipe specification.
