How Much Is 100 Milliliters of Water in Grams?

100 milliliters of water weighs 100.00 g. This is based on water having a density of 236.59g per cup. Because milliliters measure volume and grams measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 100 milliliters.

Formula and Step-by-Step

milliliters × 1g/ml = grams
  1. Start with 100 milliliters of water
  2. 1 milliliter of water = 1g
  3. 100 × 1 = 100.00g

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 Milliliter?

Most kitchen measuring cups outside the US are marked in milliliters. A standard metric cup is 250 ml. When converting American recipes, 1 US cup = 236.588 ml.

What is a Gram?

A gram (g) is a metric unit of mass equal to 1/1000 of a kilogram. It is the standard weight measurement for precise baking worldwide. Professional bakers prefer grams because they are more accurate than volume measurements.

Frequently Asked Questions

About 100.00 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 milliliters by 1 (grams per milliliter for water). For 100 milliliters: 100 × 1 = 100.00 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: 100.00 g ÷ 1 = 100 milliliters. Or use the Grams to Milliliters converter.
