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: Write down the given value

Let’s say we have a speed of 60 km/h that we want to convert to mph.

Step 3: Set up the conversion equation

We can set up a proportion using the conversion factor:

60 km/h = x mph

Step 4: Apply the conversion factor

Multiply both sides of the equation by the conversion factor (0.621371) to cancel out the kilometers and obtain the value in miles per hour:

60 km/h * 0.621371 = x mph

Step 5: Calculate the result

Using a calculator, multiply 60 by 0.621371:

37.28226 = x mph

Step 6: Round the result (if necessary)

Since mph is typically rounded to one decimal place, we can round the result to:

37.3 mph

Therefore, 60 km/h is approximately equal to 37.3 mph.

Note: If you have a different value for km/h, simply substitute that value into the equation and follow the same steps to convert it to mph.
