How many kilograms in three tones?

Answer 1

Did you mean: "How many kilograms are there in three metric tons of weight?" The answer is: 3,000 kilograms. The kilogram is a unit of mass, whereas the ton is a unit of weight. Here on planet Earth, one SI kilogram is equivalent to 0.001 tons. The value is small since the kilogram is a fairly small amount of mass (the mass of a football helmet) when compared to the ton (the average weight of a passenger vehicle). Weight and mass are not to be confused, however. One can only make a relative comparison when using a larger body, like the Earth, as a frame of reference. In fact, weight is force, and not just any force. It is a force determined by the gravitational attraction between the object weighed and the larger mass on which the object is weighed. Do not try to convert three metric tons of weight into kilograms on planet Pluto! Mass is uniform: meaning that it is the same anywhere in the Universe, whereas weight changes according to gravity.
