Microsecond

Examples

• 1 microsecond – cycle time for frequency , the inverse unit. This corresponds to radio wavelength 300 m, as can be calculated by multiplying 1 μs by the speed of light to determine the distance travelled.
• 1 microsecond – the length of time of a high-speed, commercial strobe light flash.
• 1.8 microseconds – the amount of time subtracted from the Earth's day as a result of the 2011 Japanese earthquake.
• 2 microseconds – the lifetime of a muonium particle
• 2.68 microseconds – the amount of time subtracted from the Earth's day as a result of the 2004 Indian Ocean earthquake.
• 3.33564095 microseconds – the time taken by light to travel one kilometer in a vacuum
• 5.4 microseconds – the time taken by light to travel one mile in a vacuum
• 8.01 microseconds – the time taken by light to travel one mile in typical single-mode fiber optic cable
• 10 microseconds – cycle time for frequency 100 kHz, radio wavelength 3 km
• 18 microseconds – net amount per year that the length of the day lengthens, largely due to tidal acceleration.
• 20.8 microseconds – sampling interval for digital audio with 48,000 samples/s
• 22.7 microseconds – sampling interval for CD audio
• 38 microseconds – discrepancy in GPS satellite time per day due to relativity
• 50 microseconds – cycle time for highest human-audible tone
• 50 microseconds to read – the access latency for a modern solid state drive which holds non-volatile computer data
• 100 microseconds – cycle time for frequency 10 kHz
• 125 microseconds – sampling interval for telephone audio
• 164 microseconds – half-life of polonium-214
• 240 microseconds – half-life of copernicium-277
• 250 microseconds – cycle time for highest tone in telephone audio
• 277.8 microseconds – a fourth, used in astronomical calculations by al-Biruni and Roger Bacon in 1000 and 1267 AD, respectively.
• 489.67 microseconds – time for light at a 1550 nm frequency to travel 100 km in a singlemode fiber optic cable.
• The average human eye blink takes 350,000 microseconds.
• The average human finger snap takes 150,000 microseconds.
• A camera flash illuminates for 1,000 microseconds.
• Standard camera shutter speed opens the shutter for 4,000 microseconds or 4 milliseconds.
