📏 Why Do We Need Unit Conversion?

Different countries and industries use different measurement systems. For example:

• The United States often uses inches, feet, yards, and miles (Imperial system).

• Most of the world uses millimeters, centimeters, meters, and kilometers (Metric system).

• Certain fields (like textiles, construction, science, and sports) may switch between both systems.

That’s where a unit converter becomes essential. Instead of wasting time calculating, you can get the correct result instantly.
