Formula and Step-by-Step

cups × 236.59g/cup = grams
  1. Start with 2.88 cups of water
  2. 1 cup of water = 236.59g
  3. 2.88 × 236.59 = 681.38g

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

Liquid densities vary: oils weigh less per cup than water, while syrups and honey weigh more. This is why ingredient-specific conversions matter even for liquids.

Understanding the Units

What is a Cup?

A cup is a US customary unit of volume equal to 236.588 milliliters or 8 fluid ounces. It is the most common volume measurement in American recipes. One cup can be divided into 16 tablespoons or 48 teaspoons.

What is a Gram?

Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.

Frequently Asked Questions

About 681.38 g, based on water having a density of 236.59g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 236.59 (grams per cup for water). For 2.88 cups: 2.88 × 236.59 = 681.38 g.
For the most accurate results, weigh water on a kitchen scale. If measuring by volume, use a liquid measuring cup on a flat surface and read the level at eye height.
Temperature has a minimal effect on most cooking liquids. The density of water changes slightly with temperature, but the difference is usually less than 1-2% between refrigerator and room temperature. This conversion assumes room temperature.
Reverse the conversion: 681.38 g ÷ 236.59 = 2.88 cups. Or use the Grams to Cups converter.
