Rice Grams to Cups Converter
100g of uncooked long-grain white rice is about 0.54 US cups, using our reference of 185g per cup.
Enter another dry rice weight below. This reference does not apply to cooked rice or a rice cooker's measuring cup.
Reference: The USDA's Nutritive Value of Foods, page 50 lists raw, regular long-grain enriched white rice at 185g per cup. We adopt that weight for this site's US Customary setting. The publication was revised in 2002; this is a published household-measure reference, not a new test of your rice.

Are these measurements for cooked or uncooked rice?
They are for uncooked rice. Measure the dry grains before rinsing, soaking or cooking when using this reference.
Cooked rice includes absorbed water. Its weight and volume depend on the rice and preparation, so dividing a cooked portion's weight by 185 does not give a suitable cup estimate.
This converter also does not predict how much cooked rice your dry portion will produce. Follow your recipe or rice package for water amounts and cooking directions rather than treating a grams-to-cups conversion as a cooking ratio.
Is a rice-cooker cup the same as a US cup?
Not necessarily. For example, Zojirushi lists its included rice measuring cup at approximately 180mL. Our US Customary setting uses 236.588mL, so those cups are different sizes.
If your cooker instructions say to use the supplied cup, follow that cup and the matching instructions. Do not assume the cooker's cup markings use this page's US measure. Check your model's manual rather than assuming every appliance uses the same cup.
The calculator's Metric setting is 250mL, not a 180mL rice-cooker setting. See our cup-size guide for the three supported standards.
How to measure rice for this conversion
With a scale, put an empty bowl on it, zero the display and add the requested weight of dry rice.
Without a scale, fill a dry measuring cup with loose grains and level the top. Avoid pressing the grains down to fit extra into the cup. Match the cup volume to the standard used for your conversion.
The estimate still depends on the rice. This page uses a regular long-grain white rice reference; it is not a universal weight for brown, short-grain, instant or every branded rice product. If your recipe or package supplies its own weight equivalent, follow that instead.
How to convert rice grams to cups
For this page's US Customary reference:
Cups of uncooked rice = grams ÷ 185
For example, 250 ÷ 185 = about 1.35 cups. Keep the full calculation internally and round the final answer.
To convert cups to grams, multiply by 185. Under the same reference, ½ cup is 92.5g and 2 cups is 370g. Switch direction in the calculator above, or use the cups-to-grams converter with uncooked long-grain white rice selected.
What if I use a 250mL metric cup?
Choose Metric in the calculator. Scaling the adopted reference by cup volume gives about 195.5g per metric cup. This is the site's calculated estimate, not a separate USDA metric-cup measurement.
The chart above stays on the US Customary setting. Read our methodology for the adjustment and rounding rules, or visit the grams-per-cup chart to compare ingredient references.
