The conversion from milliliters (mL) to grams (g) is a bit tricky as it involves converting a unit of volume (milliliters) to a unit of mass (grams). That is, each substance will have a different formula for conversion. Don't worry, however, as you will rarely need to do complex and complicated calculations. This type of conversion is usually used in food preparation between different measurement systems or in chemical problems. Read on to learn more!

Steps

Method 1 of 3: Basic Concepts

Convert Milliliters (mL) to Grams (g) Step 9

Step 1. Understand the mass and grams

Grams are units of pasta, that is, an amount of mass. If you crush an object to make it denser and smaller, you won't change its mass. A sachet of sugar, a paper clip and a grape are some objects that normally weigh 1 gram.

  • Grams are normally used as a unit of weight and can be measured using a scale. Weight is a measure of gravity force on mass. If you went into space, you would still have the same mass (amount of matter), but you would have no more weight since there is no more gravity.
  • Grams are usually abbreviated as g.

Step 2. Understand the volume and milliliters

Milliliters are units of volume, that is, an amount of space. A milliliter of water, a milliliter of gold and a milliliter of air occupy the same space. If you crush an object to make it denser and smaller, you will change its volume. One milliliter is usually equivalent to 20 drops of water or 1/5 of a teaspoon.

  • Milliliters are usually abbreviated as mL.

Step 3. Understand why you need to know the substance to be converted

Since these units measure different things, there is no single, quick conversion formula. You need to find out what the formula is according to what you want to measure. For example, the amount of molasses that fits in a 1 mL bottle will have a different weight compared to the amount of water that fits in the same bottle.

Step 4. Understand density

Density measures how closely an object's matter clumps together. It is possible to understand this concept even without measuring it: for example, if you pick up a metal ball and you are surprised by its weight in relation to size, a sign that it is very dense and contains a large mass agglomeration. If you pick up a paper ball of the same size, you will probably be able to throw it without too much difficulty, as it will have a lower density. Density is measured in mass per volumetric unit. For example, how much "mass" in grams does a milliliter volume fit in? That's why we use density to convert between the two measurements.

Method 2 of 3: Converting in the Kitchen

Convert Milliliters (mL) to Grams (g) Step 1

Step 1. To convert measures of flour, multiply by 0.57

There are many types of flour, but most white, wholemeal and bread flours have very similar densities. Due to the possible variation in density, however, add the flour to the recipe gradually, adapting the amount according to the appearance and consistency of the dough.

This measure was calculated based on a density of 8.5 grams per tablespoon and a conversion of 1 tablespoon = 14, 7868 mL.

Step 2. To convert measures of milk, multiply by 1, 03

Multiply the measure in mL of milk by 1.03 to get its mass (or weight) in grams. This measure is for whole milk, as skimmed milk is closer to 1.035; however, the difference is minimal for most recipes, being negligible in terms of accuracy.

Step 3. To convert measures of butter, multiply by 0, 911

Don't have a calculator handy? Multiplying by 0.9 should suffice for most recipes. Exact measurements in decimal places are not always necessary.

Step 4. To convert water measurements, do nothing

1 milliliter of water equals 1 gram of dough, weighing 1 gram in most common situations, including cooking recipes and math problems (unless otherwise stated in the statement). There is no need to do any calculations as the measurements in mL and grams are always the same.

  • This conversion is easy and is not coincidental but rather a result of how the units were defined. Many scientific units were created based on water, as it is a very common and useful substance.
  • You only need to use a different conversion if the water is much hotter or colder than the common temperatures used in everyday life.

Step 5. Use an online calculator for other ingredients

Most common foods can be converted using the aqua-calc online food calculator. One milliliter equals one cubic centimeter, so select the "cm³" option, enter the volume in milliliters and choose the food or ingredient you want to convert.

Method 3 of 3: Converting Any Substance

Convert Milliliters (mL) to Grams (g) Step 6

Step 1. Search for material density

As described above, density equals mass per volumetric unit. If you need to answer a problem in chemistry or mathematics, it is very likely that the statement will show the density of the substance. In other situations, you need to search for density on the internet or in a table.

  • Use this table to check the density of the pure elements on the periodic table. The link is only available in English, but the element names are very similar to those in Portuguese. (Attention: 1 cm3 = 1 milliliter.)
  • Use this document to check food and beverage density - the link is available in English only. For items with specific gravities listed, understand that these numbers equate to density in g/mL at 4 °C, typically being close for substances at room temperature.
  • For other substances, just search by [material name + density] in a search tool.

Step 2. Convert density to g/mL as needed

Density is sometimes presented in another unit. If it is written in g/cm3, you don't need to change anything, since a cm3 is equivalent to 1 mL. For other units, use an online density calculator or do the calculations yourself:

  • Multiply density in kg/m3 (kilograms per cubic meter) per 0.001 to obtain the density in g/ml.
  • Multiply the density in pounds/gallon (pounds sterling per US gallon) by 0.120 to get the density in g/mL.
Convert Milliliters (mL) to Grams (g) Step 8

Step 3. Multiply the volume in milliliters by the density

Multiply the measurement in mL of the substance by its density in g/mL. You will get a response in (g x mL) / mL, but you can cancel out the mL and get a result in grams only.

For example, to convert 10 ml of ethanol to grams, look for the density of ethanol: 0.789 g/ml. Multiply 10 mL by 0.789 g/ml, and you get 7.89 g. Now you know that 10 milliliters of ethanol weighs 7.89 grams

Tips

  • To convert grams to milliliters: Instead of multiplying grams by density, divide them.
  • The density of water is equal to 1 g/ml. If the density of a substance is greater than 1 g/ml, then it is denser than water and would sink if it were in the same container as it. If the density is less than 1 g/ml, this is a sign that it is less dense than water and would float in the liquid.
