Looking up the specifications of an oil online, the spec sheet indicates that the specific gravity of this oil is .93.
Does this mean that the oil weights .93 grams / 1 cubic centimeter of oil?
Specific gravity has no units but the s.g. is the same as the density if the measurement is made against water with a density of 1.00 g/cc. Therefore, the oil you looked up has a mass of 0.93 g/cc when compared to water at a density of 1.00 g/cc. Thus it is lighter than water and will float on water.
