Quick Answer
Cyclohexanone (CYC) has a density of 0.9478 g/mL at 20°C. This is equivalent to 0.9478 g/cm³, 0.9478 kg/L, and 947.8 kg/m³. At 25°C, the density of cyclohexanone decreases slightly to approximately 0.947 g/mL.
What Is Cyclohexanone Density?
Density refers to the mass of cyclohexanone per unit volume. Cyclohexanone density is typically measured in grams per milliliter (g/mL) or grams per cubic centimeter (g/cm³), which are numerically equivalent for liquids. Cyclohexanone density is normally reported at a standard reference temperature, most commonly 20°C or 25°C, because liquid density decreases slightly as temperature rises.

Why Is Cyclohexanone Density Important?
Cyclohexanone density is a critical parameter for several practical purposes in industrial purchasing and handling:
Formulation and mixing. Cyclohexanone density is used to calculate accurate mixing ratios when blending it with resins, solvents, or coating formulations by weight rather than volume.
Dosing and process control. Cyclohexanone density allows engineers to convert between volumetric dosing (liters) and mass-based process specifications (kilograms) in production lines.
Packaging and weight calculation. Cyclohexanone density determines the net weight of a given drum or IBC volume, which affects freight cost calculations and compliance with transport weight limits.
Storage tank design. Cyclohexanone density is used to calculate the total weight a storage tank will hold at full volume, which affects tank foundation and structural design requirements.
Transportation and container loading. Cyclohexanone density directly determines how many liters of product can be loaded into a container or tank truck without exceeding maximum weight limits - for example, calculating how many tons are contained in a 1,000-liter IBC tote.
How to Measure Cyclohexanone Density?
Cyclohexanone density is typically measured using standardized test methods to ensure consistency across suppliers and buyers. Common methods include:
- ASTM D4052 - Standard test method for density using a digital density meter (oscillating U-tube method)
- ASTM D1298 - Standard test method for density using a hydrometer
Cyclohexanone density values on a Certificate of Analysis (COA) are generally obtained using one of these two methods, and buyers can request the specific test method used when verifying supplier data.

FAQs
What is the density of cyclohexanone in g/mL?
Cyclohexanone has a density of 0.9478 g/mL at 20°C.
What is the density of cyclohexanone at 20°C?
At 20°C, cyclohexanone density is 0.9478 g/mL, equivalent to 947.8 kg/m³.
Is cyclohexanone heavier than water?
Yes, cyclohexanone is slightly denser than water. Water has a density of approximately 1.000 g/mL at 20°C, while cyclohexanone has a density of 0.9478 g/mL - meaning cyclohexanone is actually marginally lighter than water, not heavier, and will float on the surface of water rather than sink.
What is the specific gravity of cyclohexanone?
The specific gravity of cyclohexanone is approximately 0.948, based on its density relative to water at the same reference temperature.
How do you convert cyclohexanone density from g/mL to kg/L?
No conversion is required - g/mL and kg/L are numerically identical units for liquid density. Cyclohexanone at 0.9478 g/mL is also 0.9478 kg/L.
Why is cyclohexanone density important in industrial applications?
Cyclohexanone density is used to calculate mixing ratios, convert between volume and weight for shipping and storage, and determine tank or container loading capacity in industrial and logistics operations.
Does cyclohexanone density change with temperature?
Yes, cyclohexanone density decreases slightly as temperature increases, from approximately 0.9478 g/mL at 20°C to 0.947 g/mL at 25°C.
How is cyclohexanone density measured?
Cyclohexanone density is commonly measured using ASTM D4052 (digital density meter) or ASTM D1298 (hydrometer method) to ensure standardized, verifiable results.
What ASTM method is used to determine cyclohexanone density?
ASTM D4052 is the most commonly used method for determining cyclohexanone density in industrial quality control, using an oscillating U-tube digital density meter.
Where can I buy high-purity cyclohexanone?
High-purity industrial-grade cyclohexanone (CAS 108-94-1) is available from chemical manufacturers and suppliers who provide batch-specific COAs verifying density, purity, and water content. [Discover Gneebio's Premium Cyclohexanone Products]
