Why Weigh Water in Grams?
When a recipe calls for 1½ cups of water, using a kitchen scale to measure exactly 360 grams will give you far more consistent results than volume measurement alone. This is because water can be packed, sifted, or scooped differently each time, leading to weight variations of up to 20%.
How to Measure Water by Weight
Place your mixing bowl on a digital kitchen scale and press "tare" to zero it out. Then add water until the scale reads 360g. This method is faster than measuring cups and eliminates the guesswork entirely.
Frequently Asked Questions
1½ cups of water weighs exactly 360 grams or approximately 12.7 ounces. This is based on a standard US cup measurement of 240 grams per cup.
Yes, the density of water (240g per cup) is consistent across brands. Minor variations of ±5% may occur depending on grind, moisture, and how the ingredient is packed into the cup — which is exactly why weighing with a scale is recommended.
If measuring by cups, whether you sift can change the weight by 10-20%. When measuring by weight (360g), sifting doesn't affect accuracy since you're targeting an exact gram amount regardless of volume.
This conversion uses the US standard cup (236.6ml, commonly rounded to 240ml). If you're using a metric cup (250ml), the weight will be slightly higher. For perfect accuracy, always use a kitchen scale.
