• Common subunits include centimeters (cm) and millimeters (mm).
• 1 meter = 100 centimeters.

The Imperial System

• The Imperial System is primarily used in the United States and some other countries.
• Length units include inches, feet, yards, and miles.
• 1 foot = 12 inches.
• 1 yard = 3 feet = 36 inches.
Understanding these two systems helps us appreciate why conversions are necessary and how they relate to different measurement contexts. ---
