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

Step 1: Understand the conversion factor

1 kilometer is equal to 0.621371 miles. This is the conversion factor we will use to convert km/h to mph.

Step 2: Set up the conversion equation

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

Step 3: Perform the conversion

Let’s say we have a value of 60 km/h that we want to convert to mph. We will multiply this value by the conversion factor.

60 km/h * 0.621371 = 37.28226 mph

So, 60 km/h is equal to approximately 37.28 mph.

Step 4: Round off the result (optional)

If you want to round off the result to a certain number of decimal places, you can do so. In this case, rounding off to two decimal places, the result would be 37.28 mph.

That’s it! You have successfully converted km/h to mph using the given conversion factor.
