Understanding the Metric and Imperial Systems
The Metric System
The metric system, also known as the International System of Units (SI), is a decimal-based system of measurement that is used worldwide. It originated in France in the late 18th century and has since become the standard system for scientific and everyday measurements in most countries. The basic unit for length in the metric system is the meter (m).
The Imperial System
The imperial system, primarily used in the United States and a few other countries, is a system of measurements that includes units such as inches, feet, yards, and miles. The imperial system has historical roots dating back to the British Empire and remains prevalent in many practical applications, including road distances and speed limits.
Conversion Factors Between Kilometers and Miles
