Dichloromethane (DCM), also known as methylene chloride, is a colorless, volatile solvent used in paint stripping, metal cleaning, adhesives, and chemical processing. Its density is an important physical property for liquid handling, volume-to-weight calculations, and industrial purchasing.

What Is the Density of Dichloromethane?
The density of dichloromethane is approximately 1.32–1.33 g/cm³ at 20°C.
Published sources give slightly different values depending on measurement conditions. PubChem reports values around 1.3255–1.3266 g/cm³, while other product specifications may show a slightly different range.
For general industrial calculations, 1.32 g/cm³ at 20°C is a practical reference value.

For a specific commercial batch, buyers should refer to the supplier's TDS or COA for the specified density.
Is Dichloromethane Denser Than Water?
Yes, dichloromethane is denser than water, with a density about 1.32 times that of water.
Water has a density of approximately 1.00 g/cm³, while DCM is around 1.32–1.33 g/cm³ at 20°C. As a result, when DCM and water form separate liquid phases, DCM normally settles at the bottom.
This property is commonly used when working with DCM in liquid-liquid extraction and laboratory processes.
What Is the Density of DCM in kg/L?
The density of DCM at 20°C is approximately 1.32 kg/L.
The conversion is:
1.32 g/cm³ = 1.32 kg/L
Therefore, approximately:
- 1 L DCM ≈ 1.32 kg
- 100 L DCM ≈ 132 kg
- 1,000 L DCM ≈ 1.32 MT
Actual shipment and commercial calculations should use the density specified for the product and reference temperature.
Does DCM Density Change With Temperature?
Yes, the density of dichloromethane changes with temperature.
As temperature increases, DCM expands and its density generally decreases. This is why density values from different technical sources may vary slightly.
When comparing specifications or calculating the weight of a specific volume, always check the measurement temperature.
FAQ
What is the density of dichloromethane at 20°C?
The density of dichloromethane at 20°C is approximately 1.32–1.33 g/cm³.
Is DCM heavier than water?
Yes. DCM is denser than water and normally forms the bottom layer when the two liquids separate.
