Quilômetro

Quilômetro is the Portuguese word for kilometer. It is a unit of length in the International System of Units (SI). The prefix "quilo" indicates a factor of one thousand, so one quilômetro is equal to one thousand meters. This makes it a convenient unit for measuring longer distances, such as the length of roads, the distance between cities, or the height of mountains.

The symbol for quilômetro is "km". It is widely used in Portuguese-speaking countries for everyday measurements and in scientific contexts. For comparison, one mile is approximately equal to 1.609 kilometers. The meter, the base unit of length in the SI system, was originally defined based on the Earth's circumference. The quilômetro, therefore, indirectly relates to this fundamental measurement. Its widespread adoption has facilitated consistent communication and standardization in global trade, transportation, and scientific endeavors.
