If the volume of any substance is known, can the weight be found by the specific gravity ?
Multiply the SG of the substance by the volume, then multiply the answer by the weight of the same volume of water (1 gramme per cubic centimetre, 1000 kg per cubic metre)
E.g specific gravity of steel commonly stated as 7.85
1 cubic metre of water weighs 1000 kg
thus 1 cubic metre of steel weighs (7.85 x 1000) kilogrammes
= 7850 kg
