The speeds of computer connections, measured in milliseconds or microseconds, have become important. It produced pulses of maser emission lasting for a few hundred microseconds. Computed lifetimes are in the range of 0.1 to 10 microseconds. The interface delay is a configurable static parameter expressed in tens of microseconds. Symbol duration is 4 microseconds, which "includes" a guard interval of 0.8 microseconds. This free induction decay occurs on a timescale of 1-100 microseconds depending on instrument settings. Typically it is measured in tens to hundreds of microseconds. Each arbitration round lasts about 125 microseconds. Since a spike lasts only 10s of microseconds, the temperature rise is minimal. The range resolution was 0.25 microseconds, about . Typical switching times are in the range of microseconds. Fusion events may consist of over a half million atoms interacting for hundreds of microseconds. Microfabricated OECTs show response times of the order of hundreds of microseconds. Hindu texts describe units of Kala measurements, from "microseconds" to "trillions of years". Isotopes of unbinilium are predicted to have alpha decay half-lives of the order of microseconds.
