Nobody contributed a millisecond. Around 300 BC, the Babylonians, who worked in base 60 rather than base 10, divided the day into 60. Each unit was divided into 60, and again into 60 and so on. Conceptually, this gave them an accuracy of around 2 microseconds. "Conceptually", because they had no instruments able to measure time with anything like that precision - an hour was probably the best that they could reliably measure.
In the year 1000, al-Biruni, a Persian scholar was the first to use the term second. He divided the day into hours, 1/60 of each were minutes, 1/60 of each were seconds, 1/60 of each were thirds, 1/60 of each were fourths, The last of these was 1/3600 seconds or 0.277... recurring milliseconds.
The introduction of the decimal system brought in the prefices for thousandths (milli-) and millionths (micro-) etc, and the sequence of 60ths were abandoned.
17,300 milliseconds
60 seconds is equal to 60,000 milliseconds.
A 100th of a second is equal to 10 milliseconds.
30 milliseconds = 0.03 seconds30 milliseconds = 0.0005 minutes
Milliseconds are thousandths of a second
there are 1000 milliseconds in a second
It is 14 milliseconds.
1,000 milliseconds in one second.
185 milliseconds divided by 1000 milliseconds per second
1,000 milliseconds = 1 second 31,657 milliseconds = 31.657 seconds
Milliseconds are a unit of time. In one second, there are one thousand milliseconds.
There are 31,536,000,000 milliseconds in a non-leap year, and 31,622,400,000 milliseconds in a leap year.
