The cgs unit for measuring the viscosity of a liquid is the poise [p]: 1 p = 1 g/(s·cm). the si unit is the kg/(s·m). the viscosity of water at 5°c is 2.06 ✕ 10-3 kg/(s·m). express this viscosity in poise.

Explanation:

We have that

if the viscosity of water at 5°C is:

To express this quantity in poise, we have to go from SI units to CGS units, we can do that by replacing kilograms by grams and meters by centimeters.

we know that:

Inserting this into the preceding equation we have:

Where or centipoise is a hundredth of a poise
