Water Grams to Cups Converter

Summary

Water has a density of exactly 1 g/mL at 4 °C (close enough for all practical cooking and baking purposes). That means grams of water convert directly to milliliters, and from there to any US volume unit. This tool does the full chain — grams → mL → US cups, tablespoons, and teaspoons — in one step. Reverse conversion (cups back to grams) is also supported.

How it works

1. Enter the weight of water in grams (or US cups for the reverse direction).
2. The tool applies water's density of 1 g/mL to convert grams to milliliters.
3. Milliliters are then divided by 236.588 to get US cups.
4. Cups are multiplied by 16 for tablespoons and by 48 for teaspoons.
5. All four results update instantly as you type.

Use cases

• Scale a baking recipe that lists water in grams to cup measurements.
• Verify how much water to add when a recipe calls for a fraction of a cup.
• Convert a hydration ratio (e.g. 65% hydration = 650 g water per 1 kg flour) to cups.
• Calculate water volume for brewing coffee or tea by weight.
• Cross-check kitchen scale readings against a measuring cup.
• Convert bottled-water serving sizes listed in grams to familiar cup amounts.
