How is the prefix 'kilo' defined in terms of powers of ten?

The prefix 'kilo' is defined as 10 to the power of 3, which means it represents a factor of one thousand. In the metric system, this prefix is commonly used to denote quantities like kilometers (1,000 meters) and kilograms (1,000 grams). Understanding the power of ten system is crucial for interpreting measurements correctly in scientific and engineering contexts. The use of 'kilo' simplifies communication about large quantities by reducing the number of digits typically needed. For example, instead of writing 1,000 meters, one could simply say 1 kilometer, making it more convenient for calculations and understanding.
