Orders of magnitude (viscosity)

File:University of Queensland Pitch drop experiment.jpg

The pitch drop experiment, demonstrating the viscosity of bitumen.

This page is a progressive and labeled list of the SI dynamic viscosity orders of magnitude, with examples appended where possible.

Unless otherwise stated, all viscosities are measured at room temperature and pressure.
