How It Works
This converter works in 3 steps.
Enter the mass
Type the mass in g, kg, oz, or lb.
Enter the density
Type ρ in g/mL, kg/L, or lb/US gal, or pick a common liquid.
Read the volume
The converter returns V = m / ρ in mL, L, US fl oz, and US gal.
Reverse when needed
Type a volume instead to get the mass to weigh.
The Formula
The formula divides mass by density.
V = m / ρm = V × ρ1 g/mL = 1 kg/L = 8.345 lb/US gal- V:
- Volume
- m:
- Mass
- ρ:
- Density at the working temperature
100 g of glycerol (ρ = 1.261 g/mL) occupies 100 / 1.261 = 79.3 mL.
Conversion Table
The conversion table gives the volume of 1 kg, 100 g, and 1 lb (453.6 g) for 6 liquids.
| Liquid | Density | Volume of 1 kg | Volume of 100 g | Volume of 1 lb |
|---|---|---|---|---|
| Water (20 °C) | 0.9982 g/mL | 1,002 mL | 100.2 mL | 454.4 mL |
| Ethanol (20 °C) | 0.7893 g/mL | 1,267 mL | 126.7 mL | 574.7 mL |
| Glycerol (20 °C) | 1.261 g/mL | 793 mL | 79.3 mL | 359.7 mL |
| Seawater (3.5% salt) | 1.025 g/mL | 975.6 mL | 97.56 mL | 442.5 mL |
| Hydrochloric acid 37% | 1.19 g/mL | 840.3 mL | 84.03 mL | 381.2 mL |
| Sulfuric acid 98% | 1.84 g/mL | 543.5 mL | 54.35 mL | 246.5 mL |
What Is the Solution Mass-to-Volume Converter?
The Solution Mass-to-Volume Converter is a tool that converts a weighed mass of liquid into its volume, and back, using the liquid's density. Volume equals mass divided by density.
Weighing a liquid is faster and more accurate than measuring a viscous or volatile liquid by volume. Glycerol, syrups, and concentrated acids cling to glass, so gravimetric dispensing removes drainage error. The converter accepts g, kg, oz, and lb, and returns mL, L, US fl oz, and US gal.
Common Uses
There are 5 main uses of this converter.
Viscous liquid handling
Users weigh glycerol, Tween, and syrups instead of pipetting them.
Acid dispensing
Chemists weigh concentrated acids for exact volumes.
Batch scaling
Producers convert mass recipes to tank volumes.
Shipping documents
Shippers convert net weight to liters for labels.
Tank gauging
Operators convert load-cell mass into tank volume.
