The SI units for viscosity are N·s/m2 . Another commonly used unit for viscosity is the poise, where 10 poise = 1 N·s/m2 . The poise is a fairly large unit, and it is more common to use the centipoise. Which of the following is equal to the centipoise?
a. 10?3 N·s/m2 b. 10?2 N·s/m2 c. 10?1 N·s/m2 d. 102 N·s/m2
