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

The conversion equation is: miles per hour = kilometers per hour × conversion factor.

Step 3: Plug in the values

Let’s say you have a speed of 60 km/h that you want to convert to miles per hour. Plug this value into the equation:

miles per hour = 60 km/h × 0.621371.

Step 4: Perform the calculation

Multiply 60 km/h by 0.621371:

miles per hour = 37.28226 mph.

Step 5: Round the answer (optional)

If you want to round the answer to a certain number of decimal places, you can do so. In this case, rounding to two decimal places gives us:

miles per hour ≈ 37.28 mph.

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

Remember, the conversion factor of 0.621371 is an approximation, so the result may not be exact.
