How do you convert mL to grams?

To convert milliliters (mL) to grams, you need to know the density of the substance or ingredient you are working with, as milliliters are a unit of volume and grams are a unit of mass. Here is the step-by-step process:

Formula

The conversion formula is based on the relationship between volume, mass, and density:

[ \text{Mass (in grams)} = \text{Volume (in mL)} \times \text{Density (in g/mL)} ]

Steps

1. Identify the Volume: Determine the volume of the substance in milliliters (mL).
2. Find the Density: Look up or determine the density of the substance in grams per milliliter (g/mL).
3. Apply the Formula: Multiply the volume in milliliters by the density in grams per milliliter.

Example

• If you want to convert 15 mL of milk to grams and the density of milk is 1.04 g/mL: [ 15 \, \text{mL} \times 1.04 \, \text{g/mL} = 15.6 \, \text{grams} ]244.

Special Case: Water

For water, the conversion is simpler because the density of water is approximately 1 g/mL at room temperature. Therefore, for water:

[ 1 \, \text{mL} = 1 \, \text{gram} ]24.

Importance of Density

The density of the substance is crucial for this conversion. Different substances have different densities, so the same volume of different substances will weigh differently. For example, 1 mL of flour weighs about 0.53 grams, while 1 mL of honey weighs about 1.42 grams4.
