Why Does 1 Cup of Water Vary?
The weight of 1 cup depends on how you measure. USDA standard (spooned) = 240g.
Standard pour
Pour into measuring cup at eye level. All liquid measurements are consistent — density doesn't change with measuring technique.
ConsistentAbout Water Density
Water is the reference point for all density measurements. 1 cup (240ml) = 240g exactly. All liquid measurements in recipes assume water-like density unless specified. Use water as baseline for density calculations.
Pro tip: For consistent baking results, use a kitchen scale. Weight measurements eliminate the variability of cup measurement entirely. USDA values shown are based on the spooned & leveled method.
