1532. How to convert microseconds to seconds [µs to s]:. If it happens to land on an exact second, it returns an integer instead.// This line will not create an object when microtime returns an integer because it depends on the number being a float, including a decimal point!// This will die when format is attempted on a non-object Conversion Table from Microseconds to Seconds . What is 100 microseconds in seconds? Microseconds was established in 1992 in association with the reseller Logical Solutions as a means of facilitating the disposal of previously leased equipment from government departments, small business and educational facilities. Use the How many seconds in a microsecond? 1 Second: time of 9 192 631 770 periods of the radiation corresponding to the transition between the 2 hyperfine levels of the ground state of the caesium 133 atom at 0 K (but other seconds are sometimes used in astronomy) t s = 1.0 × 10-6 × t µs. It is the angular diameter of an object of 1 unit diameter at a distance of 360×60×60/(2pi) (approximately 206,265 units), such as (approximately) 1 cm at 2.1 km, or, directly from the definition, 1 astronomical unit at 1 parsec.The second (symbol s) is a unit for time, and one of seven SI base units. The conversions on this site will not be accurate enough for all applications. Rather than using the list() function, etc. It is defined as the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom at zero kelvins.

There are 0.000001 seconds in a microsecond.Let's take a closer look at the conversion formula so that you can do these conversions yourself with a calculator or with an old-fashioned pencil and paper.The formula to convert from microseconds to seconds is:Next, let's look at an example showing the work and calculations that are involved in converting from microseconds to seconds (μs to s).For quick reference purposes, below is a conversion table that you can use to convert from microseconds to seconds.This table provides a summary of the Time units within their respective measurement systems.Looking for a conversion?
t[µs]=1 000 000×t[s]. Period is the inverse of frequency: 1 Hz = 1 / 0.000 001 cpµs. As previously pointed out, setting the parameter $get_as_float as true will not allow microseconds precision (what would mean 6 decimal digits). Type in your own numbers in the form to convert the units! A lot of the comments here suggest adding in the following way:  (float)$usec + (float)$sec But note that the default 'precision' setting of PHP* - which is used when a float is converted to a stringy format by echo()ing, casting or json_encode()ing etc - is not enough to hold the six digit accuracy of microtime(true). Unit Descriptions; 1 Microsecond: A microsecond is exactly 1 x 10-6 seconds. Time: t[s]=1.0 × 10(in power of -6)×t[µs]. What is the difference between String and string in C#? // As of PHP 5.4.0, REQUEST_TIME_FLOAT is available in the $_SERVER superglobal array. All these timing scripts rely on microtime which relies on gettimebyday(2) Many other converters available for free. 1536. Microseconds (μs) Seconds (s) 1: 1E-06: 2: 2E-06: 3: 3E-06 To swap units ↺ Amount. To swap units ↺ Amount. 1 second is equal to 1000000 microseconds, or 1000000000 nanoseconds. Convert frequency units. Before using any of the provided tools or data you must check with a competent authority to validate its correctness. I use this for measure duration of script execution. 1 microsecond is the length of time of a high-speed, commercial strobe light flash. This output pattern was consistent on three separate machines, running OpenBSD, Mac OS X and Windows. Online calculator to convert microseconds to seconds (μs to s) with formulas, examples, and tables. A microsecond is one millionth of a second. You can use one variable to check execution $time as follow: "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ" Utilisez cet outil facile pour convertir rapidement Microsecondes en tant qu'élément de Temps Related. Of the methods I've seen here, and thought up myself, to convert microtime() output into a numerical value, the microtime_float() one shown in the documentation proper(using explode,list,float,+) is the slowest in terms of runtime. Microseconds offers a wide range of computers, peripherals and upgrades. Do a quick conversion: 1 microseconds = 1.0E-6 seconds using the online calculator for metric conversions. Please re-enable javascript in your browser settings. Return Values. //Function to convert microtime return to human readable units Note that the timestamp returned is "with microseconds", not "in microseconds". A second is the base unit of time. It is important to note that microtime(TRUE) does NOT always return a float (at least in PHP 5.x; I have not tested 7.x). By default, microtime() returns a string in the form "msec sec", where sec is the number of seconds since the Unix epoch (0:00:00 January 1,1970 GMT), and msec measures microseconds that have elapsed since sec and is also expressed in seconds.

How many seconds in a microsecond: If t µs = 1 then t s = 1.0 × 10-6 × 1 = 1.0 × 10-6 s. How many seconds in 40 microseconds: If t µs = 40 then t s = 1.0 × 10-6 × 40 = 4.0 × 10-5 s. Note: Microsecond is a metric unit of time. Use this page to learn how to convert between microseconds and nanoseconds. This is especially good to know if you pass 'true' as the parameter and then calculate the difference between two float values -- the result is already in seconds; it doesn't need to be divided by a million. A convenient way to write the current time / microtime as formatted string in your timezone as expression? From. I have been getting negative values substracting a later microtime(true) call from an earlier microtime(true) call on Windows with PHP 5.3.8 Conversions may rely on other factors not accounted for or that have been estimated. Your answer will appear in the …

Originally, it … A second of arc or arcsecond is a unit of angular measurement which comprises one-sixtieth of an arcminute, or 1/3600 of a degree of arc or 1/1296000 (approximately 7.7×10-7) of a circle. One microsecond is equal to 1 × 10-6 to unit of time second. Effectuer une conversion entre les unités (µs → s) ou consultez le tableau de conversion Note that rounding errors may occur, so always check the results. I have found the following code to be a bit cleaner and simpler:
