Conversion Formula
cups = g × 0.004227
Use the formula exactly as shown to convert between grams and cups on a water-equivalent basis.
This page uses US cups and a water-equivalent assumption. Ingredient weights vary, so the same gram value can fill a different number of cups depending on the ingredient.
Reverse
g = cups × 236.588
If you need the reverse direction, use the paired converter and keep the same water-based assumption.
How to Convert
- 1Start with the grams amountEnter the value you have, then confirm that a water-based conversion is appropriate for what you are measuring.
- 2Apply the converter formulaUse cups = g × 0.004227 to estimate the matching cups value for water or water-like liquids.
- 3Adjust if the ingredient is differentFor flour, sugar, butter, and similar ingredients, use the ingredient-specific weight if precision matters because density changes the result.
