kg m-2
kg m2
kg cm3
has no S.I unit
Εξήγηση
Note: relative density has no S.I unit
∴ Relative density = weight of substance ÷ weight of equal volume of water
RD = w1 ÷ (w1 – w2) (no S. I unit)
∴ Relative density = weight of substance ÷ weight of equal volume of water
RD = w1 ÷ (w1 – w2) (no S. I unit)
