The cooper test which was designed by Kenneth H. Cooper in 1968 for US military use is a physical fitness test. [ 1][ 2][ 3] In its original form, the point of the test is to run as far as possible within 12 minutes. Pacing is important, as the participant will not cover a maximal distance if they begin with a pace too close to an all out ...

The Army Physical Fitness Test ( APFT) was a test designed to measure the muscular strength, endurance, and cardiovascular respiratory fitness of soldiers in the United States Army. The test contained three events: push-ups, sit-ups, and a two-mile run with a soldier scoring from 0 to 100 points in each event based on performance.
One décime is equal to 10 decimal minutes, which is nearly equal to a quarter-hour (15 minutes) in standard time. Thus, "five hours two décimes" equals 5.2 decimal hours, roughly 12:30 p.m. in standard time. [ 8][ 9] One hundredth of a decimal second was a decimal tierce.
Date-time group.

Time on a ship's clocks and in a ship's log had to be stated along with a "zone description", which was the number of hours to be added to zone time to obtain GMT, hence zero in the Greenwich time zone, with negative numbers from −1 to −12 for time zones to the east and positive numbers from +1 to +12 to the west (hours, minutes, and ...
A minute of arc is π 10 800 of a radian . A second of arc, arcsecond (arcsec), or arc second, denoted by the symbol ″, [ 2] is 1 60 of an arcminute, 1 3600 of a degree, [ 1] 1 1 296 000 of a turn, and π 648 000 (about 1 206 264.8) of a radian. These units originated in Babylonian astronomy as ...
