vacuum permittivity ε0,
Planck constant h,
These are the constant having no unit!

Thank you !
Hope it helps ......

07161020: and permeability of a fluid too
realsujaykumar: no its unit is m sq
realsujaykumar: or darcy
Unnatiraj: No brother it's right
realsujaykumar: permeability measures in darcy (d); 1 d = 10 ^ -12 m^2 (approx)
realsujaykumar: the unit of h is jule-second and the unit of vaccum permitivity is farad per meter (F/m)
07161020: yeah and stress too
realsujaykumar: he he its unit is N/m^2
