Target Volume Mass Calculator
The Target Volume Mass Calculator tells you how many grams or kilograms to weigh out to reach a target volume of a liquid.

How Target Volume Mass Calculator Works?
The Target Volume Mass Calculator works in 3 steps.
- 1
Enter the target volume you need, in liters (L) or milliliters (mL).
- 2
Set the liquid density, for example 0.789 g/mL for ethanol or 1.26 g/mL for glycerin.
- 3
Weigh out the calculated mass on a scale instead of measuring the volume in glassware.
Target Volume Mass Calculator Formula
The Target Volume Mass Calculator formula is:
Mass (kg) = Target volume (L) × Density (kg/L)Mass (g) = Target volume (mL) × Density (g/mL).
Worked example
For 250 mL of glycerin, weigh 250 × 1.26 = 315 g.
Weighing beats volumetric measuring for thick liquids. Glycerin and syrups cling to cylinder walls and leave 1% to 3% behind; a scale records the full amount.
Target Volume Mass Calculator Conversion Table
The Target Volume Mass Calculator table lists the grams (g) to weigh out for 8 target volumes of 4 laboratory liquids.
| Target volume | Ethanol (g) | Isopropyl Alcohol (g) | Acetone (g) | Glycerin (g) |
|---|---|---|---|---|
| 10 mL | 7.89 | 7.86 | 7.84 | 12.6 |
| 30 mL | 23.67 | 23.58 | 23.52 | 37.8 |
| 50 mL | 39.45 | 39.3 | 39.2 | 63 |
| 100 mL | 78.9 | 78.6 | 78.4 | 126 |
| 250 mL | 197.25 | 196.5 | 196 | 315 |
| 500 mL | 394.5 | 393 | 392 | 630 |
| 1 L | 789 | 786 | 784 | 1,260 |
| 5 L | 3,945 | 3,930 | 3,920 | 6,300 |
What is Target Volume Mass Calculator?
The Target Volume Mass Calculator is a tool that calculates the mass needed to produce a chosen volume of a substance. The calculator runs the volume-to-mass direction of the density formula and suits gravimetric filling and lab preparation.
Gravimetric dosing (dosing by weight) gives better repeatability than volumetric dosing. A 0.01 g lab balance measures 10 mL of ethanol to ± 0.1%, while a 10 mL measuring cylinder reads to about ± 1%.
What are the uses of Target Volume Mass Calculator?
There are 4 main uses of the Target Volume Mass Calculator: lab solutions, cosmetics, gravimetric filling and sample shipping.
Lab solutions
Chemists weigh solvents to make up exact volumes of standard solutions.
Cosmetics
Formulators weigh glycerin and alcohol for 30 mL and 50 mL product batches.
Gravimetric filling
Bottling lines fill by weight to a declared volume.
Sample shipping
Labs calculate the mass of a 1 L sample for courier declarations.
Target Volume Mass Calculator FAQ
How many grams is 100 mL of ethanol?
100 mL of ethanol weighs 78.9 g at 0.789 g/mL.
Why weigh a liquid instead of measuring volume?
Weighing is faster and more repeatable, and scales are easier to calibrate than glassware.
