Cups to Grams Converter
cups

g
Calculation: g = cups × 236.588
Conversion Formula
g = cups × 236.588
Use the formula exactly as shown to convert between cups and grams on a water-equivalent basis.
This page uses US cups and a water-equivalent assumption. Ingredient weights vary, so flour, sugar, butter, and other ingredients will not match the same gram value.
Reverse
cups = g × 0.004227
If you need the reverse direction, use the paired converter and keep the same water-based assumption.
How to Convert
- 1Start with the cups amountEnter the value you have, then confirm that a water-based conversion is appropriate for what you are measuring.
- 2Apply the converter formulaUse g = cups × 236.588 to estimate the matching grams 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.

Frequently Asked Questions
QIs cups to grams exact for every ingredient?
No. This page uses a water-equivalent assumption. Different ingredients have different densities, so the same cup value can weigh more or less in grams.
QWhen is this cups to grams conversion useful?
It is useful for water, water-like liquids, and rough kitchen estimates when you need a quick volume-to-weight comparison.
QWhat formula should I use for cups to g?
Use g = cups × 236.588. For the reverse direction, use cups = g × 0.004227.
QWhy do recipe charts show different values?
Recipe charts often use ingredient-specific densities. A cup of flour, sugar, and water will each convert to different gram values.
QHow do I convert back from grams to cups?
