Reynold number = I.F/V.F.
Froude number = (I.F/G.F)^0.5.
Mach number = (I.F/E.F)^0.5.
Euler number = (I.F/P.F)^0.5.
Weber number = (I.F/S.T)^0.5.

I.F Inertia force.
V.F Viscous force.
G.F Gravity force.
E.F Elastic force.
P.F Pressure force.
S.T Surface tension.

Frode number is ratio of inertia and gravitational force, Euler number is the ratio of inertia and pressure force, weber number is the ratio of inertia and surface tension, Reynolds number is the ratio of inertia and viscous force.
