ft/s 3.2808 The metre per second is the unit of both speed (a scalar quantity ) and velocity (a vector quantity , which has direction and magnitude) in the International System of Units (SI), equal to the speed of a body covering a distance of one metre in a time of one second .
Under-18 world best performances in the sport of athletics are the best marks set in competition by athletes aged 17 or younger throughout the entire calendar year of the performance. World Athletics (formerly IAAF) maintains an official list for such performances, but only in a specific list of outdoor events.
In the United States and elsewhere, athletes previously ran the 220-yard dash (201.168 m) instead of the 200 m (218.723 yards), though the distance is now obsolete. The standard adjustment used for the conversion from times recorded over 220 yards to 200 m times is to subtract 0.1 seconds, [ 1 ] but other conversion methods exist.
