	Hi all, I have a question in relation to density calculation. D=M/V, so DxV=M and therefore V=M/D. V = M / (0.998), so V = M . 1.002 (the inverse of 0.998) Taking the Density of water at room temp to be 0.998 kg/m3, what I want to know is this: If the unit of density (0.998) is kg/m3, when you invert it, what is the unit of the 1.002 figure? Is there a name for this?

	hi, Density of water at room temp is 998kg/m3( not .998kg/m3). Anyway the reciprocal of density is specific volume. Its unit is m3/kg.

	Density = Mass /volume At normal conditions density of water is 1000 kg/m3 which means 1000 kg of water needs space of 1 m3.Recirocal of density is Specific volume Its unit is m3/kg. Terms like specific volume, specific enthalpy etc are used to solve numerical and many practical problems.
