The svedberg (S or Sv) is a unit of time used in chemistry equal to one hundred femtoseconds (100 fs). The shake is a unit of time used in nuclear physics equal to ten nanoseconds (10 ns). The sigma is a unit of time equal to one microsecond (1 μs). The jiffy is sometimes used to mean a unit of time of 10 ms. [dubious – discuss]

The conversion from continuous time to samples (discrete-time) changes the underlying Fourier transform of () into a discrete-time Fourier transform (DTFT), which generally entails a type of distortion called aliasing. Choice of an appropriate sample-rate (see Nyquist rate) is the key to minimizing that distortion.
This amounted to 34.1% of all seaborne trade for the year. [4] Combining the amount carried with the distance it was carried, oil tankers moved 11,705 billion metric-ton-miles of oil in 2005. [63] By comparison, in 1970 1.44 billion metric tons of oil were shipped by tanker. [64] This amounted to 34.1% of all seaborne trade for that year. [65]
For example, a stiff and compact object dropped from 1 m that impacts over a distance of 1 mm is subjected to a 1000 ɡ 0 deceleration. [citation needed] Jerk is the rate of change of acceleration. In SI units, jerk is expressed as m/s 3; it can also be expressed in standard gravity per second (ɡ 0 /s; 1 ɡ 0 /s ≈ 9.81 m/s 3). [citation needed]
TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion.The ton of TNT is a unit of energy defined by convention to be 4.184 gigajoules (1 gigacalorie), [1] which is the approximate energy released in the detonation of a metric ton (1,000 kilograms) of TNT.
It is also frequently useful in general relativity to express mass in units of length or time. M ☉ G / c 2 ≈ 1.48 km (half the Schwarzschild radius of the Sun) M ☉ G / c 3 ≈ 4.93 μs; The solar mass parameter (G·M ☉), as listed by the IAU Division I Working Group, has the following estimates: [20] 1.327 124 420 99 (10) × 10 20 m 3 s ...
