How to use this demo page...

If you add a query string to the URL in the browser, you can display the speeds in different units. For example, add &unit_speed=mph to display the units in miles per hour. Alternatively, use the links below.

• default
• mph
• kts
• kph
• source
• null

You can also adjust the rounding, by adding a fidelity query string to the URL. For example, &fidelity=0.000 will change the rounding to three decimal points.
