Dynamic viscosity occurs in a gas or liquid as resistance to the non-accelerated displacement (constant flow) of adjacent layers.

where:
• newton second per square meter = N•s•m^(-2) = m^(-1)•kg•s^(-1)
• dyne second per square cm = dyn•s•cm^(-2) = cm^(-1)•g•s^(-1)
• poundal second per square foot = pdl•s•ft^(-2) = ft^(-1)•lb•s^(-1)
Implementation: Convert input units to newton second per square meter, then from newton second per square meter to the output units.
