To convert miles per hour (mph) to kilometers per hour (km/h), you can use the following step-by-step instructions:

Step 1: Understand the conversion factor

1 mile is equal to approximately 1.60934 kilometers. This conversion factor will be used to convert miles to kilometers.

Step 2: Set up the conversion equation

To convert mph to km/h, you need to multiply the given value in mph by the conversion factor.

Conversion equation: km/h = mph × 1.60934

Step 3: Perform the conversion

Multiply the given value in mph by the conversion factor to obtain the equivalent value in km/h.

For example, let’s convert 60 mph to km/h using the conversion equation:

km/h = 60 mph × 1.60934

Step 4: Calculate the result

Multiply the given value in mph by the conversion factor to get the equivalent value in km/h.

km/h = 60 × 1.60934

km/h = 96.5604

Therefore, 60 mph is equal to approximately 96.5604 km/h.

Remember to round the final result to an appropriate number of decimal places based on the level of accuracy required.

Note: If you are using a calculator, you can directly multiply the given value in mph by 1.60934 to obtain the result in km/h.
