Answer
You are mixing up your terminology. A 'tonne' is spoken as 'metric ton'. There is no such thing as a 'metric tonne'; it's simply a 'tonne'.
0.0075 metric tonnes.
i barrel = ?? Metric tonnes
About 800,000 pounds or 362.87 metric tons (tonnes).
19.47 million metric tonnes
To convert barrels of oil to metric tonnes, you can use the approximate conversion factor of 0.136 metric tonnes per barrel. Therefore, 4,000,000 barrels of oil is roughly equivalent to about 544,000 metric tonnes (4,000,000 barrels × 0.136 tonnes/barrel). However, this can vary slightly depending on the type of crude oil, as different oils have different densities.
1 litre of water weighs 1kg. 1 metric tonne is 1000kg. 500kg is 0.5 metric tonnes so there are 500 litres (of water) in 0.5 tonnes. 1 imperial ton = ~1016kg (1.016 metric tonnes)
The answer is 1,672 tonne (metric ton).
6 metric tonnes is 192,904.479 troy ounces.
3000 kg is 3 tonnes.
66,000 pounds is 29.94 metric tons.
1 metric ton = 1,000 kilograms
To convert liters to metric tonnes, you need to know the density of the liquid. For water, which has a density of 1 kg/L, 5000 liters would weigh 5 metric tonnes. If the liquid is denser, the weight in metric tonnes would be higher.
