- Hz to MHz conversion calculator How to convert megahertz to hertz. 1Hz = 0.000001MHz. 1MHz = 1000000Hz. Megahertz to hertz formula. The frequency f in hertz (Hz) is equal to the frequency f in megahertz (MHz) times 1000000.
- A microsecond is equal to 1000 nanoseconds or 1⁄1,000 of a millisecond. Because the next SI prefix is 1000 times larger, measurements of 10 −5 and 10 −4 seconds are typically expressed as tens or hundreds of microseconds.

- La mejor manera que se me ocurre definitivamente es cambiando tu formato de fecha en mysql por un tipo int 20 y usar microtime en PHP. Pero como no se puede cambiar el formato, puedes intentar que los segundos se guarden en un formato de numeracion 25 lo que da una capacidad de combinacion de 625 numeros (algo asi como hexadecimal pero en lugar de 16 es a 25) donde entrarian un equivalente.
A microsecond is an SI unit of time equal to one millionth (0.000001 or 10 −6 or 1 ⁄ 1,000,000) of a second. Its symbol is μs, sometimes simplified to us when Unicode is not available. A microsecond is equal to 1000 nanoseconds or 1 ⁄ 1,000 of a millisecond.
This animation illustrates the generation of the debris and ejecta clouds after a spherical aluminum projectile impacts a thin aluminum plate at approximately 7 km/s. The frame interval is about 1 microsecond.

Examples[edit]
- 1 microsecond (1 μs) – cycle time for frequency1×106hertz (1 MHz), the inverse unit. This corresponds to radio wavelength 300m (AM medium wave band), as can be calculated by multiplying 1 μs by the speed of light (approximately 3.00×108 m/s) to determine the distance travelled.
- 1 microsecond – the length of time of a high-speed, commercial strobe light flash (see air-gap flash).
- 1.8 microseconds – the amount of time subtracted from the Earth's day as a result of the 2011 Japanese earthquake.[1]
- 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.[2]
- 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 (or radio waves point-to-point in a near vacuum)
- 8.01 microseconds – the time taken by light to travel one mile in typical single-mode fiber optic cable
- 10 microseconds (μs) – cycle time for frequency 100 kHz, radio wavelength 3km
- 18 microseconds – net amount per year that the length of the day lengthens, largely due to tidal acceleration.[3]
- 20.8 microseconds – sampling interval for digital audio with 48,000 samples/s
- 22.7 microseconds – sampling interval for CD audio (44,100 samples/s)
- 38 microseconds – discrepancy in GPSsatellite time per day (compensated by clock speed) due to relativity[4]
- 50 microseconds – cycle time for highest human-audible tone (20 kHz)
- 50 microseconds to read – the access latency for a modern solid state drive which holds non-volatile computer data[5]
- 100 microseconds (0.1 ms) – cycle time for frequency 10 kHz
- 125 microseconds – sampling interval for telephone audio (8000 samples/s)
- 164 microseconds – half-life of polonium-214
- 240 microseconds – half-life of copernicium-277
- 250 microseconds – cycle time for highest tone in telephone audio (4 kHz)[citation needed]
- 277.8 microseconds – a fourth (a 60th of a 60th of a second), used in astronomical calculations by al-Biruni and Roger Bacon in 1000 and 1267 AD, respectively.[6][7]
- 489.67 microseconds – time for light at a 1550 nm frequency to travel 100 km in a singlemode fiber optic cable (where speed of light is approximately 200 million meters per second due to its index of refraction).
- The average human eye blink takes 350,000 microseconds (just over 1/3 of one second).
- The average human finger snap takes 150,000 microseconds (just over 1/7 of one second).
- A camera flash illuminates for 1000 microseconds.
- Standard camera shutter speed opens the shutter for 4000 microseconds or 4 milliseconds.
