Interesting fact: The weight of a city includes buildings, infrastructure, vehicles, and people, totaling billions of kilograms.
The answer: A medium-sized city can weigh between 100 and 500 million metric tons (1 × 10^11 to 5 × 10^11 kg), depending on its size and density.
A city's weight encompasses all its physical components: buildings made of concrete, steel, and glass; roads and bridges; vehicles; and the population itself. For example, a city like San Francisco, with dense urban structures, weighs hundreds of millions of metric tons. This mass impacts urban planning, infrastructure maintenance, and environmental considerations.
