This tool converts speeds from miles per hour to various other units for you.

## How to Use the MPH to KM/H Conversion Calculator

To convert values between miles per hour (mph) and kilometers per hour (km/h), you can use this simple calculator:

- Enter a value in either the ‘Miles per hour (mph)’ or the ‘Kilometers per hour (km/h)’ input field.
- Click the “Calculate” button.
- The converted result will be displayed in the ‘Result’ field.

## Explanation of Calculation

The calculator converts values between miles per hour (mph) and kilometers per hour (km/h) using these formulas:

- To convert mph to km/h: multiply the mph value by 1.60934.
- To convert km/h to mph: divide the km/h value by 1.60934.

It automatically determines which conversion to perform based on the input provided.

## Limitations

This calculator assumes a direct linear conversion and does not account for any more complex factors. Ensure that only numbers are entered in the inputs to prevent errors.
