Same answer as if you replaced the word "nanoseconds" with the word "years".Let me show you how to do it:What is faster, 210 years or 2 years ?Now can you guess ?
It is one millisecond ;)
1000 nanoseconds = 1 microsecond
A microsecond as there are 1000 microseconds in a millisecond
3.335640952 x 10^-9 nanoseconds If Einstein is right and light is a constant, and your measuring a straight line. You can not measure something moving faster than the constant speed of light moving through a nanometer worth of space, if you were to it would have to move faster than 3.335640952 x 10^-9 nanoseconds per nanometer. That is the maximum potential measurement of time in a nanometer on a straight line.
The millisecond is a unit of time, not a unit of speed.100 milliseconds is 100 times longer than one millisecond.
1 microsecond equals 0.001 milliseconds
40,000 times as fast
