If 1 litre of water weighs 1 kg, then how many cubic millimetres of water will weigh 0.1 gm?

Question

Aicharya · Accepted Answer

1 litre of water weighs 1 kg = 1000 gm, and 1 litre $= 1{,}000{,}000$ cubic millimetres (since 1 litre $= 1000$ cm³ and 1 cm³ $= 1000$ mm³). So 1000 gm corresponds to $1{,}000{,}000$ mm³, meaning 1 gm corresponds to 1000 mm³. Therefore 0.1 gm corresponds to $0.1 	imes 1000 = 100$ cubic millimetres.
