Reports generally indicate wind velocity in miles or knots per hour or meters per second. If your data shows the wind speed in kilometers per hour, simple mathematics allows you to convert the speed into miles per hour. To simplify the process, use a calculator and make sure to double-check your work. The final answer in miles should be a smaller number than the speed in kilometers, as one mile is equivalent 1.61 kilometers.

1
Turn on the calculator.
-
2
Enter the speed in kilometers per hour. For example, enter 100 for 100 km/h.

3
Divide the wind speed in kilometers per hour by 1.61. This will yield the wind speed in miles per hour. For example, dividing 100 km/h by 1.61 yields a wind speed of 62 mph.
