Ingredient Profile
Water has a density of 236g per cup, based on USDA FoodData Central data. The baseline liquid density — 236.588g per cup at standard kitchen temperature.
Density can shift with brand, moisture content, or how the ingredient was packed before it reached your kitchen. Weighing on a scale removes that guesswork.
For comparison, honey is denser at 340g per cup, while panko breadcrumbs is lighter at 60g per cup — a reminder that weight per cup varies by ingredient, not by category alone.
How to Measure Water in Cups
Use a liquid measuring cup on a flat surface and check the measurement at eye level, not from above.
Set the measuring cup on a flat, stable surface before pouring, since checking the fill line while holding the cup can introduce a slight reading error from an uneven angle.
If a recipe calls for water by weight instead of volume, a digital kitchen scale set to grams removes any measuring-technique variation entirely — the converter at the top of this page shows both figures side by side so you can check your result either way.
Water vs Other Liquids
Ingredients in the same category don't always share a similar density. Here's how water compares to other liquids on this site.
| Ingredient | Grams per Cup | vs Water |
|---|---|---|
| Water | 236g | baseline |
| Vanilla Extract | 208g | -12% |
Common Recipe Uses

Frequently Asked Questions
How many grams are in a cup of water?+
A cup of water weighs about 236g. The baseline liquid density — 236.588g per cup at standard kitchen temperature.
How do I measure water accurately?+
Use a liquid measuring cup on a flat surface and check the measurement at eye level, not from above.
Does water's weight per cup ever change?+
Yes, slightly. The baseline liquid density — 236.588g per cup at standard kitchen temperature. A kitchen scale removes that variation entirely.
What's the best way to convert water from grams to cups?+
Use the converter at the top of this page, or divide your gram amount by 236 to get cups.
Why does water weigh a different amount per cup than other liquids?+
Even within the same category, particle size, moisture, and packing differ enough to change the weight-per-cup figure by 10-30%. That's why this page uses a value measured specifically for water, not a category-wide average.
Is 236g per cup the same across every brand of water?+
It's close for most brands, though minor milling, processing, or moisture differences can shift the true figure by a few grams. USDA / NIST provides the reference value used here.
