Viscosity of Common Alcohols
The viscosity of alcohols generally increases with the size of the alcohol molecule. The following table provides a curated list of dynamic (absolute) viscosity values for various alcohols at standard room temperature (approximately 20°C or 68°F) and 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
