# Encyclopedia

A millisecond (from milli- and second; abbreviation: ms) is a thousandth (1/1000) of a second.

10 milliseconds (a hundredth of a second) are called a centisecond

There are 86400000 (24×60×60×10×10×10) milliseconds in one day.

To help compare orders of magnitude of different times, this page lists times between 10−3 seconds and 100 seconds (1 millisecond and one second). See also times of other orders of magnitude.

• 1 millisecond (1 ms) – 1000 cycles in 1 frequency 1 kHz
• 1 millisecond – duration of light for typical photo flash strobe
• 1 millisecond – time taken for sound wave to travel ca. 34 cm.
• 1 millisecond – repetition interval of GPS C/A PN code
• 1.000692286 milliseconds – time taken for light to travel ca. 300 km in a vacuum
• 2 milliseconds – the amount the length of the day increases per day per century as a result of tidal friction from the Moon [1]
• 2.27 milliseconds – cycle time for the A above middle C in music (440 Hz); if a tuning device for musical instruments generates just one tone, it is probably this tone
• 3 milliseconds – a housefly's wing flap
• 4 milliseconds – typical average seek time for a 10000 rpm hard disk
• 5 milliseconds – a honey bee's wing flap
• 8 milliseconds – 1/125 of a second (125), a standard camera shutter speed; fastest shifting time of a car's mechanical transmission
• 10 milliseconds (10 ms) – cycle time for frequency 100 Hz
• 11 milliseconds - the latency on a spektrum Dx7SE radio
• 16.7 milliseconds (1/60 second)– a third. Also called a jiffy. Cycle time for American 60 Hz AC mains grid
• 20 milliseconds – cycle time for European 50 Hz AC mains grid
• 33.3 milliseconds – the amount of time one frame lasts in 30fps video
• 41.708 milliseconds - the amount of time one frame lasts in 24fps video or film (actually 23.976fps for most films.)
• 50 milliseconds – cycle time for the lowest audible tone, 20 Hz
• 60 milliseconds – cycle time for European 16.7 Hz AC electrified railroad power grid
• 62.5 milliseconds - a sixty-fourth note at MM = 60
• 30 to 100 milliseconds – typical minimum latency for a broadband internet connection (important for online gaming)
• 100 milliseconds – the reaction speed of a human
• 125 milliseconds – a thirty-second note at MM = 60
• 134 milliseconds – time taken by light to travel around the earth's equator
• 150 milliseconds – recommended maximum time delay for telephone service
• 200 milliseconds – the time it takes the human brain to recognize emotion in facial expressions
• 250 milliseconds – recommended maximum time delay for a computer terminal or web page
• 250 milliseconds – an approximate average of the round trip time for communications via geosynchronous satellites
• 250 milliseconds – a sixteenth note at MM = 60
• 430 to 500 milliseconds – common modern dance music tempos (120 - 140 BPM)
• 300 to 400 milliseconds – the blink of a human eye
• 400 milliseconds – time in which the fastest baseball pitches reach the strike zone
• 500 milliseconds – an eighth note at MM = 60
• 860 milliseconds: average human resting heart rate

# Simple English

A millisecond (sometimes shortened to 'ms') is one thousandth of a second.

This page lists times between 10−3 seconds and 10−2 seconds (1 millisecond to 10 milliseconds).

• shorter times
• 1 millisecond – the time it takes for a normal flash in a camera to finish.
• 1 millisecond – time taken for sound to travel 34 cm
• 1.000692286 milliseconds – time taken for light to travel 300 km in a vacuum
• 2 milliseconds – half life of hassium-265
• 3 milliseconds – a housefly’s wing flap
• 3.4 milliseconds – half life of meitnerium-266
• 5 milliseconds – a honey bee’s wing flap
• 8 milliseconds – 1/125 of a second (125), a camera shutter speed
• 9 milliseconds – normal seek time for a 7200rpm hard disk
• longer times
