How to Convert Pascal second to Poise

Converting Pascal second (Pa·s) to Poise (P) is a core calculation in Dynamic Viscosity, which quantifies a fluid's internal tangential resistance to shear deformation and laminar flow. This calculation bridges modern MKSA metric standards with the historical Gaussian centimetre-gram-second (CGS) electrostatic and electromagnetic framework. In CGS systems, electromagnetic units (such as statvolts, abvolts, dynes, ergs, and gauss) are formulated directly from mechanical dimensions, with electrostatic-to-electromagnetic relations tied to the speed of light in vacuum (c ≈ 2.99792458 × 1010 cm/s). Exactly 1 Pascal second translates to 10 Poise (1 P = 0.1 Pa·s).

Mathematical Conversion Derivation via Coherent SI Base Unit

Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (pascal second (Pa·s)) without arbitrary rounding:

Vtarget=Vsource×(ksource→SIktarget→SI)V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)
Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)
1. Source SI Bridge (ksource):1 Pa·s = 1 pascal second (Pa·s)
2. Target SI Bridge (ktarget):1 P = 0.1 pascal second (Pa·s)
Step-by-step substitution for Pascal second → Poise:V(P) = V(Pa·s) × ( 1 / 0.1 ) = V(Pa·s) × 10
Mathematical FormulaValue in Poise = Value in Pascal second × 10Direct computational formula applied for standard conversion.
Worked Example

To convert 50 Pascal second (Pa·s) to Poise (P): multiply 50 by 10 to get 500 P. At an industrial engineering scale, 1000 Pa·s converts to 10000 P.

Inverse check: 1 P = 0.1 Pa·s.

Frequently Asked Questions

The mathematical formula to convert pascal seconds to poise is: [value] * 10 = poise. Rather than doing the math manually, you can use our high-precision online calculator to process this exact equation instantly without rounding errors.

To perform the reverse calculation from poise back to pascal seconds, you must divide your starting value by 10. Our bidirectional tool automatically computes this inverse equation the moment you type into the poise input field.

1 Pascal second is larger than 1 Poise. Specifically, 1 Pascal second equals exactly 10 poise, making it 10 times larger (a difference of 1.00 orders of magnitude). Therefore, quantities expressed in poise require a larger numerical value to represent the same physical amount.

Under standard international measurement guidelines, 1 Pascal second converts to 10 poise. Precise numerical conversion factors ensure consistency across laboratory, engineering, and field data.

There are exactly 10 poise in 1 Pascal second (1 Pa·s = 10 P). The Pascal second is the SI coherent unit of dynamic viscosity (1 Pa·s = 1 N·s/m² = 1 kg/(m·s)), whereas the poise is the CGS absolute unit (1 P = 1 dyn·s/cm² = 0.1 Pa·s).

To convert dynamic viscosity from Pascal seconds (V(Pa·s)) to Poise (V(P)), multiply by 10:
V(P) = V(Pa·s) × 10

To convert dynamic viscosity from Poise (V(P)) to Pascal seconds (V(Pa·s)), multiply by 0.1 or divide by 10:
V(Pa·s) = V(P) × 0.1
V(Pa·s) = frac{V(P)}{10}

Liquid water at 20°C has a dynamic viscosity of 1.0016 mPa·s (0.0010016 Pa·s), equal to 0.010016 P (1.0016 cP). Motor oil SAE 30 at room temperature measures approximately 0.2 Pa·s (2 P or 200 cP), demonstrating fluid resistance in mechanical lubrication systems.
