1.0973. The foot per second (plural feet per second) is a unit of both speed (scalar) and velocity (vector quantity, which includes direction). [1] It expresses the distance in feet ( ft) traveled or displaced, divided by the time in seconds ( s ). [2] The corresponding unit in the International System of Units (SI) is the meter per second .

The length of 1 minute of latitude is 1.853 km (1.151 statute miles) (1.00 nautical miles), while the length of 1 second of latitude is 30.8 m or 101 feet (see nautical mile).
10−15 s. A femtosecond is a unit of time in the International System of Units (SI) equal to 10 −15 or 1⁄1 000 000 000 000 000 of a second; that is, one quadrillionth, or one millionth of one billionth, of a second. [ 1] For context, a femtosecond is to a second as a second is to about 31.71 million years; a ray of light travels ...
10,000 metres is the slightly longer metric derivative of the 6-mile (9,656.1-metre) run, an event common in countries when they were using the imperial measurement system. 6 miles was used in the Commonwealth Games until 1966 and was a championship in the United States in non-Olympic years from 1953 to 1973.
On February 2, 2007, KNXV-TV (with the help of the Arizona Department of Weights and Measures) reported that three of Subway's "Giant Sub" sandwiches, normally each 3 feet (91 cm) long, were actually only 2 ft 8 in, 2 ft 8 + 1 ⁄ 4 in, and 2 ft 8 + 1 ⁄ 2 in (81, 81.9, and 82.6 cm) long. Under Arizona regulations, objects cannot be more than ...
Reflected sunlight from the Moon's surface takes 1.2–1.3 seconds to travel the distance to the Earth's surface (travelling roughly 350 000 to 400 000 kilometres). 10 −6: 1.58 × 10 −5 ly: One astronomical unit (the distance from the Sun to the Earth). It takes approximately 499 seconds (8.32 minutes) for light to travel this distance. [28 ...
The light-second is a unit of length useful in astronomy, telecommunications and relativistic physics. It is defined as the distance that light travels in free space in one second, and is equal to exactly 299 792 458 m (approximately 983 571 055 ft or 186 282 mi ). Just as the second forms the basis for other units of time, the light-second can ...
