How many second in 1 milliseconds? The answer is 0.001. We assume you are converting between second and millisecond. You can view more details on each measurement unit: second or milliseconds The SI base unit for time is the second. 1 second is equal to 1000 milliseconds. Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between seconds and milliseconds. Type in your own numbers in the form to convert the units!

1 second to milliseconds = 1000 milliseconds
2 second to milliseconds = 2000 milliseconds
3 second to milliseconds = 3000 milliseconds
4 second to milliseconds = 4000 milliseconds
5 second to milliseconds = 5000 milliseconds
6 second to milliseconds = 6000 milliseconds
7 second to milliseconds = 7000 milliseconds
8 second to milliseconds = 8000 milliseconds
9 second to milliseconds = 9000 milliseconds
10 second to milliseconds = 10000 milliseconds
You can do the reverse unit conversion from milliseconds to second, or enter any two units below:
The second (symbol s) is a unit for time, and one of seven SI base units. 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.
The SI prefix "milli" represents a factor of 10-3, or in exponential notation, 1E-3.
So 1 millisecond = 10-3 arcseconds.
The definition of a second is as follows:
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. 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.
