Formula and Step-by-Step

cups × 236.59g/cup = grams
  1. Start with 3 cups of water
  2. 1 cup of water = 236.59g
  3. 3 × 236.59 = 709.77g

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

Measuring Tip

For liquids, place your measuring cup on a flat surface and read at eye level. The bottom of the meniscus (the curve at the surface) should align with the measurement line.

Understanding the Units

What is a Cup?

There are three cup standards used worldwide. The US cup (236.588 ml) is used in American recipes. The metric cup (250 ml) is standard in Australia, New Zealand, and some parts of Asia. The imperial cup (284.131 ml) appears in older British and Canadian recipes. A metric cup holds about 5.7% more than a US cup, while an imperial cup holds about 20% more. Using the wrong standard can noticeably affect a recipe.

What is a Gram?

Grams are the preferred unit in professional kitchens and bakeries because they allow exact recipe scaling. To double a recipe, simply double the gram values. No need to worry about how tightly an ingredient is packed into a cup.

Frequently Asked Questions

About 709.77 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 3 cups: 3 × 236.59 = 709.77 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: 709.77 g ÷ 236.59 = 3 cups. Or use the Grams to Cups converter.
