The sixtieth part of a minute of time or of a minute of space, that is, the second regular subdivision of the degree; as, sound moves about 1,140 English feet in a second; five minutes and ten seconds north of this place.
A unit of measurement; one minute contains 60 seconds; one degree contains 3600 seconds.
The fundamental unit of time in the International System of Units, defined as the duration of 9,192,631,770 periods of the radiation corresponding to the transition between two hyperfine levels of the ground state of cesium 133.
The sixtieth part of a minute of latitude or longitude.
An angular measurement which is 1/60th of a minute.
Basic unit of time equal to 1/86,000 of the mean solar day. The second is subdivided into tenths, hundredths, thousandths (milliseconds), millionths (microseconds), thousand-millionths (nanoseconds) and billionths (picoseconds).
Navigational term. 1/60th of a minute. Represented as ". One second equals 31 metres.
The basic unit of time in the International System of Units, equal to the duration of 9,192,631,770 cycles of radiation in a transition, or energy level change, of the cesium atom. A second is also a sixtieth part of a minute of time.
an indefinitely short time; "wait just a moment"; "it only takes a minute"; "in just a bit"
a particular point in time; "the moment he arrived the party began"
a 60th part of a minute of arc; "the treasure is 2 minutes and 45 seconds south of here"
a certain fraction of time needed, for the unit black hole to evaporate
a certain number of vibrations in a specific atom(I don't remember the name)
a totally arbitrary unit of "time
a unit by which humans measure this property
a unit of time equal to one sixtieth of a minute
The SI-System of Units defines the second as an atomic Time normal for reasons of an immense improve ...
The basic unit of measure of time, equivalent to "the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium-133 atom." For our purposes, one "second" is 1/60th of a minute.
The basic unit of time measurement, now defined as the time it takes for the magnetic field of a cesium atom to flip polarity 9,192,631,770 times, as measured by an atomic clock.
Basic unit of time (abbr. s or sec), corresponding to one 86,000th part of the mean solar day, i.e. the duration of rotation, about its own axis, of an ideal Earth describing a circle round the Sun in one year, at a constant speed and in the plane of the Equator. After the Second World War, atomic clocks became so accurate that they could demonstrate the infinitesimal irregularities (a few hundreths of a second per year) of the Earth's rotation about its own axis. It was then decided to redefine the reference standard; this was done by the 13th General Conference on Weights and Measures in 1967, in the following terms: "The second is the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the fundamental state of the atom of caesium 133". Conventionally, the second is subdivised into tenths, hundredths, thousendths (milliseconds), millionths (microseconds), thousand-millionths (nanoseconds) and billionths (picoseconds).
One sixtieth of a minute which is one sixtieth of a degree which is one 360th of a circle. Used in metes and bounds descriptions when astronomic bearings are used to describe directions.
Second, the SI base unit of time, is the duration of 9 192 631 770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom (133Cs).
A unit of measurement for time in the SI, MKS, English, and CGS systems.
The second (s) is the base unit of time in the SI system of units, defined as the duration of 9,192,631,770 cycles of the radiation associated with a certain color of light emitted by the cesium atom.
A quantitative measurement used in the metes and bounds legal description method represented by the symbol "'. An angle N 30' 10' 5" E would be read as "North thirty degrees, ten minutes, 5 seconds Fast."
The second (symbol: s; abbreviation: sec.) is the name of a unit of time, and is the International System of Units (SI) base unit of time.
