Masses of large objects
The weight of a large truck can reach several tens of tons (a short ton is 2000 lb, a metric ton has a mass of 1000 kg which is about 2200 lb or 10% larger than a short or British ton).
The weight of an aircraft carrier can reach about 100,000 tons.
Therefore the mass of the earth must be much larger than 100,000,000 kg which is the mass of 100,000 metric tons.
