* Density of water: The density of water is approximately 1000 kg/m³. This means 1 cubic meter of water weighs 1000 kilograms.

* Metric ton: A metric ton is equal to 1000 kilograms.

Calculation:

1. Convert metric tons to kilograms: 1 metric ton = 1000 kg

2. Divide the weight by the density: 1000 kg / 1000 kg/m³ = 1 m³

Therefore, 1 metric ton of water is equal to 1 cubic meter.
