The viscosity converter is a free online tool that helps you convert between physics units quickly and accurately. It supports 5 units including Pascal-second (Pa·s), Centipoise (cP), Poise (P), Stoke (St), Centistoke (cSt). The core conversion formula is: 1 Pa·s = 1000 cP = 10 P. For example, 1 Pascal-second equals approximately 1,000 Centipoise. Conversely, 1 Centipoise equals approximately 0.001 Pascal-second. Common conversions: 5 Pa·s = 5,000 cP, 10 Pa·s = 10,000 cP, 25 Pa·s = 25,000 cP, 50 Pa·s = 50,000 cP, 100 Pa·s = 100,000 cP. This converter is useful for students, engineers, scientists, and professionals who need accurate physics unit conversions. Whether you are working on homework, technical specifications, research data, or everyday measurements, this tool provides instant, reliable results. All conversions are calculated relative to a single base unit for consistency and precision across all supported units. Water at 20°C has a viscosity of about 0.001 Pa·s or 1 centipoise. Honey is about 1000 times more viscous than water.
