Baking and cooking are often about precision, especially when following recipes. You might find yourself puzzled when a recipe lists ingredients in grams, but you’re more comfortable measuring in milliliters, or vice versa. The question “How Many Ml In A Gram?” frequently pops up in kitchens everywhere. While it’s a common question, the answer isn’t always a simple one because it depends on what you’re measuring. Let’s break down the relationship between grams and milliliters and simplify ingredient conversions for your culinary adventures.
Grams and Milliliters: Weight vs. Volume Explained
To understand the conversion, it’s crucial to first differentiate between grams (g) and milliliters (mL). Grams are a unit of mass – essentially, how much “stuff” is in something, often used to measure weight in everyday contexts. Milliliters, on the other hand, are a unit of volume – how much space something occupies, typically used for liquids.
Think of it like this: a gram measures how heavy something is, while a milliliter measures how much space it takes up. They are different measurements, but they are related through a concept called density.
The Role of Density in Grams to mL Conversion
Density is the key factor when converting between grams and milliliters. Density is defined as the mass per unit volume. For water, the density is approximately 1 gram per milliliter (1 g/mL). This is why, for water specifically, 1 gram is equal to 1 milliliter.
However, not all ingredients have the same density as water. Ingredients like oil, milk, flour, and sugar have different densities, meaning that 1 gram of each of these will occupy a different volume in milliliters.
To convert grams to milliliters accurately, you need to know the density of the specific ingredient you are measuring. The formula for conversion is:
Volume (mL) = Mass (g) / Density (g/mL)
Let’s take an example. Milk has a density of roughly 1.03 g/mL. If you have 100 grams of milk and want to know the volume in milliliters:
Volume (mL) = 100 g / 1.03 g/mL ≈ 97 mL
So, 100 grams of milk is approximately 97 milliliters. As you can see, it’s slightly less than 100 mL because milk is slightly denser than water.

Convenient Grams to mL Conversion Chart for Common Ingredients
While you can calculate the conversion using the density formula, it’s often more convenient to use a conversion chart, especially when cooking or baking. Here’s a handy chart for some common kitchen ingredients to help you quickly estimate conversions between grams and milliliters:
| Volume (mL) | Water (g) | Milk (g) | Cooking Oil (g) | All-Purpose Flour (g) | Granulated Sugar (g) |
|---|---|---|---|---|---|
| 1 mL | 1 g | 1.04 g | 0.88 g | 0.53 g | 0.7 g |
| 2 mL | 2 g | 2.08 g | 1.76 g | 1.06 g | 1.4 g |
| 3 mL | 3 g | 3.12 g | 2.64 g | 1.59 g | 2.1 g |
| 4 mL | 4 g | 4.16 g | 3.52 g | 2.12 g | 2.8 g |
| 5 mL | 5 g | 5.2 g | 4.4 g | 2.65 g | 3.5 g |
| 6 mL | 6 g | 6.24 g | 5.28 g | 3.18 g | 4.2 g |
| 7 mL | 7 g | 7.28 g | 6.16 g | 3.71 g | 4.9 g |
| 8 mL | 8 g | 8.32 g | 7.04 g | 4.24 g | 5.6 g |
| 9 mL | 9 g | 9.36 g | 7.92 g | 4.77 g | 6.3 g |
| 10 mL | 10 g | 10.4 g | 8.8 g | 5.3 g | 7 g |
| 15 mL | 15 g | 15.6 g | 13.2 g | 7.95 g | 10.5 g |
| 20 mL | 20 g | 20.8 g | 17.6 g | 10.6 g | 14 g |
| 25 mL | 25 g | 26 g | 22 g | 13.25 g | 17.5 g |
| 30 mL | 30 g | 31.2 g | 26.4 g | 15.9 g | 21 g |
Important Notes on Using the Chart:
- Approximation: These conversions are approximate. For precise baking, especially in recipes where ingredient ratios are critical (like in pastry or bread making), using a kitchen scale to measure in grams is highly recommended for accuracy.
- Ingredient Variation: Density can slightly vary depending on the specific type of ingredient. For example, different types of cooking oils might have slightly different densities. Similarly, the density of flour can change based on how it’s packed (sifted vs. unsifted).
- Liquids vs. Dry Ingredients: The chart includes both liquids (water, milk, oil) and dry ingredients (flour, sugar). Notice how the gram weight for the same volume (mL) differs significantly between them due to density differences. Dry ingredients are generally less dense than liquids.
FAQs About Grams and Milliliters in Cooking
Let’s address some frequently asked questions to further clarify the relationship between grams and milliliters in the kitchen:
What exactly is a gram (g)?
A gram is a fundamental unit of mass in the metric system. It’s defined as one-thousandth of a kilogram. In cooking and baking, grams are used to precisely measure the weight of both liquid and dry ingredients, offering more accuracy than volume measurements, especially for dry ingredients.
What exactly is a milliliter (mL)?
A milliliter is a unit of volume in the metric system, defined as one-thousandth of a liter. Milliliters are commonly used to measure liquids and are equivalent to cubic centimeters (cc). In cooking, mL is used for measuring liquid ingredients like water, milk, and oils.
Is 1 gram always equal to 1 milliliter?
No, 1 gram is only equal to 1 milliliter when you are measuring a substance with a density of exactly 1 g/mL, which is approximately the density of pure water. For other ingredients with different densities, the gram to milliliter conversion will vary.
Why is it important to understand grams to mL conversion in cooking and baking?
Understanding these conversions is crucial for recipe accuracy. Recipes, especially in baking, often rely on precise ingredient ratios for the desired outcome. Using incorrect measurements due to misunderstanding grams and milliliters can significantly affect the texture, taste, and overall success of your dish. Using grams for dry ingredients and milliliters for liquids (or grams for both with conversion knowledge) improves consistency in your cooking and baking results.
Enhance Your Cooking Conversions
Mastering the grams to mL conversion is a valuable skill for any home cook or baker. While for water the conversion is straightforward (1g = 1mL), remembering that density plays a crucial role for other ingredients will help you navigate recipes with confidence. Utilizing conversion charts and understanding the basic principles of density will make your time in the kitchen more efficient and your recipes more successful.
