A millisecond (from milli- and second; symbol: ms) is a thousandth (0.001 or 10−3 or 1/1,000) of a second.〔New Oxford Dictionary〕 10 milliseconds (a hundredth of a second) are called a centisecond. 100 milliseconds (one tenth of a second) are called a decisecond. To help compare orders of magnitude of different times, this page lists times between 10−3 seconds and 100 seconds (1 milli ==Examples== *1 millisecond (1 ms) — cycle time for frequency 1 kHz; duration of light for typical photo flash strobe; time taken for sound wave to travel ca. 34 cm; repetition interval of GPS C/A PN code *1.000692286 milliseconds — time taken for light to travel 300 km in a vacuum *2 milliseconds to 5 milliseconds - typical response time in LCD computer monitors, especially high-end displays *2.27 milliseconds — cycle time for A440 (pitch standard), the most commonly used pitch for tuning musical instruments *3 milliseconds — a housefly's wing flap *3.3 milliseconds — normal delay time between initiation and detonation of a C4 explosive charge *4 milliseconds — typical average seek time for a 10,000 rpm hard disk *5 milliseconds — a honey bee's wing flap *5 milliseconds to 80 milliseconds — a hummingbird's wing flap *8 milliseconds — 1/125 of a second, a standard camera shutter speed (125); fastest shifting time of a car's mechanical transmission *10 milliseconds (10 ms) — a jiffy, cycle time for frequency 100 Hz *15.625 milliseconds — a two hundred fifty-sixth note at 60 BPM *16.67 milliseconds (1/60 second) — a third, cycle time for American 60 Hz AC electricity (mains grid) *16.68 milliseconds (1/59.94 second) — the amount of time one field lasts in 29.97 fps interlaced video (commonly erroneously referred to as 30 fps) *20 milliseconds — cycle time for European 50 Hz AC electricity *31.25 milliseconds — a hundred twenty-eighth note at 60 BPM *33.367 milliseconds — the amount of time one frame lasts in 29.97 fps video (most common for NTSC-legacy formats) *41.667 milliseconds — the amount of time one frame lasts in 24 fps video (most common cinematic frame rate) *41.708 milliseconds — the amount of time one frame lasts in 23.976 fps video (cinematic frame rate for NTSC-legacy formats) *50 milliseconds — the time interval between gear changes on a Lamborghini Aventador *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 *60 milliseconds — the time interval between gear changes on a Ferrari 458 Spider *62.5 milliseconds — a sixty-fourth note at 60 BPM *5 to 80 milliseconds — typical latency for a broadband internet connection (important for playing online games) *100 milliseconds — the time interval between gear changes on a Ferrari FXX *125 milliseconds — a thirty-second note at 60 BPM *134 milliseconds — time taken by light to travel around the Earth's equator *150 milliseconds — recommended maximum time delay for telephone service *185 milliseconds — the duration of a full rotation of the main rotor on Bell 205, 212 and 412 helicopters (normal rotor speed is 324 RPM) *200 milliseconds — the time it takes the human brain to recognize emotion in facial expressions *250 milliseconds — a sixteenth note at 60 BPM *300 to 400 milliseconds — the time for the human eye to blink *400 milliseconds — time in which the fastest baseball pitches reach the strike zone *430 to 500 milliseconds — common modern dance music tempos (120–140 BPM) *495 milliseconds — an approximate average of the round trip time for communications via geosynchronous satellites *500 milliseconds — an eighth note at 60 BPM *860 milliseconds — average human resting heart cycle time *1000 milliseconds — one second; the period of a 1 Hz oscillator *86,400,000 (24 × 60 × 60 × 1000) milliseconds — one day *31,556,908,800 (86,400,000 × 365.242) milliseconds — one year 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Millisecond」の詳細全文を読む スポンサード リンク
