1916 P. C. McIlhiney in Jrnl. Industr. & Engin. Chem. 8 434/1 It would therefore seem to be a rational procedure to use the name ‘poise’ in the way suggested by Deeley and Parr, to use the ‘centipoise’ which is one-hundredth the size of this as a unit for practical measurements.
1935 Jrnl. Royal Aeronaut. Soc. 39 916 Gasoline viscosities range from about 0·40 centipoises to 0·50 centipoises at 30° C.
1962 J. T. Marsh Self-smoothing Fabrics xi. 160 The final value of the viscosity is expressed in centipoises, against the value of unity for water.
2001 F. A. Morrison Understanding Rheol. i. 3 With the help of your coworkers, you carry out the measurement of flow rate for P = 15 psi and calculate the viscosity of your coating fluid to be 4.2 centipoise.
