Exapoise [EP]

Exapoise, abbreviated as EP, is a unit of dynamic viscosity in the metric system that represents an extremely high level of fluid resistance. One exapoise equals 10¹⁸ poise, making it suitable for describing substances far more viscous than conventional liquids. Dynamic viscosity measures a fluid’s internal resistance to flow when subjected to shear or tensile stress, and it plays a critical role in engineering, materials science, and astrophysics. While everyday fluids like water, honey, or motor oil have viscosities measured in centipoise or poise, exapoise is typically used in theoretical studies or extreme physical conditions, such as modeling the behavior of ultra-dense matter, planetary interiors, or exotic materials at high pressures and low temperatures. Understanding the properties of fluids in the exapoise range allows scientists and engineers to simulate complex phenomena like magma flow in planetary cores, highly viscous polymer production, or the movement of supercooled substances. Though exapoise is rarely encountered in practical applications, it provides a useful reference point in the hierarchy of viscosity units, which spans from the incredibly low femtopoise to the immensely high petapoise. Its inclusion in scientific discussions emphasizes the vast range of fluid behaviors that exist in nature and engineered systems.

Picopoise [pP]

Picopoise, symbolized as pP, is a unit of dynamic viscosity in the centimeter-gram-second (CGS) system, used to measure extremely low-viscosity fluids. One picopoise equals 10⁻¹² poise, making it suitable for describing fluids with very little internal resistance to flow, such as rarefied gases or micro-scale liquid films. This unit is mainly applied in advanced physics, nanotechnology, and microfluidics research, where standard units like poise or centipoise are too large to capture subtle variations in fluid behavior. Picopoise allows scientists and engineers to quantify minute differences in viscosity at molecular or atomic scales, enabling precise modeling of fluid dynamics in specialized systems. While the SI system typically uses Pascal-seconds (Pa·s) for viscosity, picopoise provides a convenient CGS-based measure for ultra-low viscosity conditions. Understanding viscosity at the picopoise level is essential in applications such as gas dynamics under low pressure, nanoscale lubrication, and highly sensitive laboratory experiments, helping researchers predict fluid behavior and design micro- and nano-scale devices with accuracy.
