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

Let’s say you have a speed of 60 mph that you want to convert to km/h. Using the conversion equation, you can calculate it as follows:

km/h = 60 mph × 1.60934

km/h = 96.5604

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

Step 4: Round the result (optional)

If you want to round the result to a specific number of decimal places, you can do so. For example, rounding the result to two decimal places, the final conversion would be:

km/h ≈ 96.56

So, 60 mph is approximately equal to 96.56 km/h.

Remember, this conversion factor is an approximation, and the exact value of 1 mile in kilometers is 1.60934.
