A nautical mile is slightly longer than a mile on land, equaling 1. But why use a different measurement system for marine navigation? Using latitude and longitude coordinates is more practical for long-distance travel, where the curvature of the Earth becomes a factor in accurate measurement.

Step 1 Measure the wind speed using an anemometer, a simple device you can find at your local hardware store. Step 2 Convert a wind speed measured in kilometers per hour to mph: Divide the kilometers per hour wind speed by 1. Step 3 Calculate a miles per hour wind speed in feet per hour, then divide by the number of feet in a knot. Distances and speeds described using the nautical mile are more relevant to map-reading than distances and speeds that utilize the conventional mile.

Multiply the wind speed given in knots or KTS by 1. For example, a wind speed of 6. Divide the wind speed given in MPH by 1. For example, a wind speed of
