The Core Measurement: Uncooked Jasmine Rice in Grams
For home cooks and professional chefs alike, precision in the kitchen is key, and this is especially true when it comes to cooking rice. The question, "how many grams does 1 cup of jasmine rice weigh?" has a nuanced answer. The most accepted average for a standard US cup of uncooked jasmine rice is approximately 190 grams. However, depending on how you scoop and level the rice, this number can fluctuate slightly. Some sources indicate a range of 185 to 200 grams, highlighting the inherent inconsistency of volume-based measurements.
Why Volume Measurements Are Inconsistent
Volume, measured in cups, is not a reliable indicator of mass, which is measured in grams. The amount of air trapped between the grains of rice can vary dramatically. If you lightly scoop the rice and level it off, you'll get a different weight than if you pack it tightly into the measuring cup. For baking or specific nutritional tracking, this small variance can make a significant difference. Using a digital kitchen scale eliminates this variable, ensuring you use the exact same quantity every time, regardless of how fluffy or compact the rice is.
Uncooked vs. Cooked: A Weighty Difference
The weight of jasmine rice changes dramatically once it is cooked. When rice absorbs water during the cooking process, its mass increases significantly. A single cup of uncooked rice, weighing around 190 grams, will yield much more than one cup of cooked rice. The cooked version of a single cup of rice typically expands to fill multiple cups and weighs more than the original uncooked grain, often reaching 195-200 grams per cooked cup, but the overall mass from the original 190g is much greater once water is absorbed.
The US Cup vs. The Rice Cooker Cup
An important distinction to make is the difference between a standard US measuring cup and the small, plastic "rice cup" that often comes with a rice cooker. The rice cooker cup is not a standard US cup measurement. It is a traditional Japanese measuring unit called a go, which holds roughly 180ml or about 150 grams of uncooked short-grain rice. This is a frequent source of confusion for many home cooks. Always check your appliance's manual or use a digital scale for best results. When using a rice cooker, it is best practice to use the provided cup for measuring both rice and water to maintain the correct ratio.
How to Measure 1 Cup of Jasmine Rice Accurately
To achieve consistent results, follow these steps for measuring jasmine rice:
- Use a Digital Scale: Place a bowl on your digital kitchen scale and tare it to zero. Scoop rice into the bowl until you reach your desired weight, such as 190g for one uncooked US cup.
- Scoop and Level: If you must use a measuring cup, use a dry measuring cup. Scoop the rice into the cup until it overflows, then use a straight edge, like the back of a knife, to sweep across the top, ensuring it is perfectly level.
- Avoid Packing: Do not tap the cup or press down on the rice, as this will compact the grains and lead to a heavier measurement than intended, throwing off your liquid ratio.
Common Rice Weight Conversions
To put the measurement of jasmine rice into context, here is a comparison table showing the approximate weight of one US cup for various uncooked rice varieties:
| Rice Type | Approximate Weight (g) per 1 US Cup |
|---|---|
| Jasmine Rice | 185-200g |
| Basmati Rice | ~210g |
| Short-Grain White Rice | ~210g |
| Arborio Rice | ~220g |
| Brown Rice | ~210g |
| Sushi Rice | ~225g |
A Simple and Reliable Jasmine Rice Cooking Method
For perfect, fluffy jasmine rice on the stovetop, remember that measuring by weight is best. The ideal ratio is typically 1 part rice to 1.25 parts water by volume, but can be fine-tuned with a scale. For example, if you measure 380 grams of uncooked rice, use approximately 475ml of water.
- Thoroughly rinse the rice in cold water until the water runs clear. This removes excess starch, which prevents the rice from clumping.
- Combine the rice and water in a saucepan with a tight-fitting lid.
- Bring the mixture to a boil over medium-high heat.
- Once boiling, reduce the heat to the lowest setting, cover the pot, and let it simmer for 15-20 minutes, or until all water has been absorbed.
- Remove the pot from the heat and let it rest, covered, for 10 minutes. This steaming period is crucial for perfect texture.
- Fluff the rice with a fork before serving.
Conclusion
Determining how many grams does 1 cup of jasmine rice weigh is more straightforward with a kitchen scale. While a volume-based measurement is a decent starting point, the most consistent and accurate results for cooking and nutritional tracking come from measuring by weight. Whether you are using a standard US measuring cup or the smaller rice cooker cup, understanding the weight conversions and best practices will help you achieve flawlessly cooked jasmine rice every time. Embrace the digital scale for superior cooking precision.

How many grams does 1 cup of jasmine rice weigh? A Comparison of Volume vs. Weight
| Measurement Method | Approx. Weight (Uncooked) | Advantages | Disadvantages |
|---|---|---|---|
| US Measuring Cup | 185-200g | Widely available, quick for rough estimates | Inconsistent due to packing density |
| Digital Kitchen Scale | Precisely 190g (or other target) | Highly accurate, consistent results, good for tracking macros | Requires extra equipment, slightly slower process |
| Rice Cooker Cup | ~150g (short-grain) | Convenient for rice cooker's water-to-rice ratio | Confusing, non-standard unit of volume |
Final Takeaway
For cooking success, switch from cup measures to a digital scale. The standard estimate of 190 grams for one uncooked cup of jasmine rice is a great reference, but a scale offers undeniable consistency. This small change in technique can lead to a big improvement in your culinary results.
