How Our Tool Works

The converter first changes your input to meters. It then converts meters to the target unit. These exact rates guide each step.

• 1 kilometer equals 1000 meters
• 1 centimeter equals 0.01 meters
• 1 millimeter equals 0.001 meters
• 1 inch equals 0.0254 meters
• 1 foot equals 0.3048 meters
• 1 yard equals 0.9144 meters
• 1 mile equals 1609.344 meters

Result formatting follows simple rules. For values one or more the result shows four decimals. For values from 0.0001 to under 1 it shows six decimals. For very large or tiny values it shows scientific notation. Scientific notation shows a number as a times ten to a power.

You also see a conversion factor line when units differ. A conversion factor tells how many target units match one source unit. The factor uses scientific notation with four digits.
