A millisecond is 1/1000 of a second. So, there are 1000 milliseconds in a second. Now… there are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and 365.25 days in a year – so:60 X 60 X 24 X 365.25 is the number of seconds, and then multiply this by 1000: 31,557,600 X 1000 = 31,557,600,000 milliseconds

Technically all of the above answers are wrong. The mean solar day is 24 hours and 2 milliseconds long (the Earth’s rotation has slowed a bit since we defined the length of a second and day).So, there are 86400002 milliseconds in a day, giving us 31536000730 milliseconds in a year.

Get the number of seconds in one sidereal year which is 31,556,926.2797 seconds and multiply it by 1000 and you get 31,556,926,279.7 milliseconds accurate to one decimal..
