How Metric and Imperial Systems Differ
The metric system relies on standardized base-10 increments, such as millimeters, centimeters, meters, and kilometers. In contrast, the US Customary and British Imperial systems leverage traditional scales including inches, feet, yards, and miles. Converting between these units requires strict multiplication constants.
