Density is the ratio of mass to volume for a substance.

Specific gravity is density compared to density of water (For gases, it is often compared to the density of air).

Viscosity is the degree to which a liquid resists flowing. Water flows easily and has low viscosity. Oil is more viscous, grease is viscous to the point where you could debate whether it is a liquid or a soft solid (a lump retains its shape and doesn't slump). Viscosity is usually a strong function of temperature, for fats, oil, grease.

Google is a good tool to find more formal definitions for these terms.

There is no general conversion. Oil is more viscous than water, but heavy oils, approaching the density of water, are more viscous than lighter oils.

"The really important thing to keep in mind is that there is no correlation [means r =~0] between viscosity and specific gravity. "

What shall be the viscosity if the specific gravity is 1.54 at 20c
