About Water
Water is the reference liquid for kitchen conversions: 1 ml equals 1 gram at normal cooking precision. This makes water useful for converting cups, grams, milliliters, and fluid ounces in hydration and baking recipes. It is also commonly known as h2o.
Water has a density of 1 g/ml when measured using the Spoon & Level method. As a liquid ingredient, the measurement method does not affect volume - grams to cups conversion is consistent.
This ingredient belongs to the liquid category and is classified as a liquid ingredient. Per 100g, it provides 0 calories,0g protein, 0g carbohydrates, and 0g fat.
Density data sourced from NIST US customary cup volume and water density at kitchen precision. US Cup = 236.588ml (NIST). Results are estimates - actual volume may vary by ±5% depending on brand and batch.
