You are watching: What is the mass of one liter of water

Then why go 1 liter the water at max density (4 °C) have a massive of 1 kg? Is it a only coincidence?

It is no a coincidence. As the Wikipedia short article on the Litre says:

One litre of water has actually a mass of almost exactly one kilogram once measured at its maximal density, which wake up at about 4 °C. Similarly: one millilitre (1 mL) of water has actually a mass of about 1 g; 1,000 litres the water has actually a fixed of about 1,000 kg (1 tonne). This connection holds due to the fact that the gram was originally identified as the mass of 1 mL of water; however, this definition was exit in 1799 due to the fact that the density of water changes with temperature and, an extremely slightly, v pressure.

1 liter of water amounts to $1 mathrmkg$ weight.1 liter that water is likewise the exact same as $1000 mathrmcm^3$ i.e. Cubic centimeter ($10 mathrmcm imes10 mathrmcm imes10 mathrmcm$ in volume) and1 liter is the exact same as 1 cubic decimeter (10 centimeters is 1 decimeter).

Therefore 1 cubic meter volume is the very same as 1000 cubic decimeter or 1000 liters and that is why 1000 liters of water weighs $1000 mathrmkg$ or 1 ton.Similarly, $1 mathrmcm^3$ is the exact same as $1 mathrmml$ and weighs $1 mathrm g$ the water.

It is not a mere coincidence however a simple equivalence measurement in between the Metric system and the SI system of measurements.
