Pressure $$[P] = \left[ {{F \over A}} \right] = \left[ {{{ML{T^{ - 2}}} \over {{L^2}}}} \right] = [M{L^{ - 1}}{T^{ - 2}}]$$

And, dimensions of Young's modulus $$[Y] = \left[ {{{Stress} \over {Strain}}} \right] = [M{L^{ - 1}}{T^{ - 2}}]$$

[Force] $ = [ML{T^{ - 2}}]$

[Momentum] $ = [ML{T^{ - 1}}]$

[Coefficient of viscosity] $$ = [M{L^{ - 1}}{T^{ - 1}}]$$
