You may not be familiar with all of the units present. Feet per second and miles per hour are commonly used units in countries that use the imperial system, such as the United States, the United Kingdom or Australia. On the other hand, meters per second and kilometers per hour are the units of choice for those nations that use the Metric system, i.e., the rest of the world. If you are looking to take to the high seas, then knots are your units of choice (they are used regardless of your affiliation to the Imperial or the Metric systems). One knot equals one nautical mile per hour (approximately 1.151 mph).
