Given 1 litre = 1 kg. We know that 1 m3 (1 cubic metre) is exactly 1000 Litres. =>1000 litre = 109 cubic millimetres. (How? 1 m x 1 m x 1 m = 100 cm x 100 cm x 100 cm = 1000 mm x 1000 mm x 1000 mm = 109 mm3) =>1 litre = 106 cubic millimetres = 1 kg = 1000 gm So 0.1 gram = 102 mm3 = 100 cubic millimetres.
