90 grams is approximately 0.379 cups.
To convert grams to cups, you must know the density or weight-to-volume relationship of the ingredient, since grams measure weight and cups measure volume. For many dry ingredients like flour or sugar, 1 cup weighs about 237 grams, but this varies by ingredient. Here, a standard conversion for all-purpose flour is used.

Conversion Formula
The formula to convert grams (g) into cups is:
cups = grams ÷ grams per cup
Because grams measure weight and cups measure volume, we need a conversion factor that relates the two. For flour, 1 cup is about 237 grams. So, dividing the grams you have by 237 gives the equivalent volume in cups.
Example calculation for 90 g:
- Start with 90 grams.
- Divide 90 by 237: 90 ÷ 237 ≈ 0.379
- So, 90 grams equals approximately 0.379 cups.
Conversion Example
- Example: 120 g to cups
- Take 120 grams.
- Divide by 237: 120 ÷ 237 ≈ 0.506.
- Result: about 0.506 cups.
- Example: 75 g to cups
- Start with 75 grams.
- Divide 75 by 237: 75 ÷ 237 ≈ 0.316.
- So, it equals around 0.316 cups.
- Example: 100 g to cups
- Use 100 grams.
- Divide 100 by 237: 100 ÷ 237 ≈ 0.422.
- The conversion is approximately 0.422 cups.
- Example: 50 g to cups
- Take 50 grams.
- Divide 50 by 237: 50 ÷ 237 ≈ 0.211.
- Equals about 0.211 cups.

Conversion Definitions
g (gram): A gram is a metric unit of mass equal to one-thousandth of a kilogram. It is used worldwide to measure small quantities of substances, mainly in cooking and science. Grams measure weight and depend on the object’s mass regardless of volume or shape.
cups: A cup is a volume measurement, commonly used in cooking in the US and some other countries. One US cup equals 236.588 milliliters. The cup measures how much space a substance occupies rather than how heavy it is. Different ingredients fill cups differently due to density.
Conversion FAQs
Why does 90 grams not equal 0.5 cups?
Because grams and cups measure different things—weight and volume, respectively—their values don’t match directly. For flour, 1 cup is about 237 grams, so 90 grams is less than half a cup. The conversion depends on the ingredient density, so 90 grams can be less or more than 0.5 cups according to what you measure.
Is the conversion from grams to cups the same for all ingredients?
No, conversions differ by ingredient since each has unique density. For example, 90 grams of flour occupies more volume than 90 grams of sugar. Therefore, you must know which ingredient you convert to get accurate cup measurements.
Can I use this conversion for liquids too?
Not exactly. Liquids often have different densities and sometimes their grams-to-cups ratio varies. Water’s conversion is easier because 1 cup of water weighs approximately 236 grams, but other liquids may differ, so this formula suits dry ingredients better.
Why does the conversion tool use 237 grams per cup?
The value 237 grams per cup is a rounded average for all-purpose flour density. It reflects the weight of one US cup of sifted flour. Different flours or packing methods may change this number, but 237 grams is a practical standard for many cooking needs.
How accurate is this grams-to-cups conversion?
This conversion offers approximate results because measuring volume by cups can vary by how ingredients are packed or sifted. Weight in grams remains consistent, so weighing ingredients is more precise, but cups provide a practical estimate for everyday cooking.
