Orders of magnitude (viscosity)

The pitch drop experiment, demonstrating the viscosity of bitumen.

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

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