Why Water = 1:1 (grams to ml)?
🧪 Water's Unique Property
Water has a density of exactly 1 g/ml at 4°C (39°F). This means 1 gram of water = 1 milliliter of water.
📏 Easiest Conversion
Unlike flour or sugar, water's weight equals its volume in metric. 240ml water = 240g water (at room temperature).
🌡️ Temperature Effect
Water density changes slightly with temperature, but the difference is negligible in cooking (less than 1% between 0-100°C).
Common Water Measurements in Baking
Bread & Pizza Dough
- • Bread loaf: 1-1.5 cups (240-360g) water
- • Pizza dough: ¾ cup (180g) water per 2 cups flour
- • Bagels: 1 cup (240g) water for 6 bagels
- • Hydration %: Water weight ÷ Flour weight × 100
Cakes & Batters
- • Chocolate cake: 1 cup (240g) boiling water
- • Pancakes: 1.5 cups (360g) water or milk
- • Crepes: 2 cups (480g) water or milk
- • Waffles: 1¾ cups (420g) water or milk

Water Measurement Tips
💧 Use Liquid Measuring Cup
For water, always use a liquid measuring cup (with spout) placed on a flat surface. Read at eye level for accuracy.
⚖️ Kitchen Scale is Best
For precision, weigh water on a kitchen scale. Place bowl, press "tare," add water until it reads 240g for 1 cup.
🌡️ Room Temperature Water
Unless recipe specifies "cold" or "boiling," use room temperature water (20-25°C / 68-77°F) for consistent results.
