Why is a meter 100 cm?

A meter is defined as 100 centimeters because the metric system was designed for simplicity and ease of conversion. The prefix "centi-" means one-hundredth, so a centimeter is one-hundredth of a meter. This decimal-based system allows for straightforward calculations and conversions between different units of measurement. The choice of 100 as a base for centimeters aligns with the metric system's emphasis on uniformity and scalability.
