What is the Mu (μ) symbol mean when looking at some time based views

Question

When I'm profiling I can see some data with ms (for milliseconds) but I also see μs. What does μs mean in JProfiler?

Also worth noting that `ns` is nano-second or 1/1000th of a μs. e.g. `System.nanoTime()` — Peter Lawrey, Mar 15 '12 at 13:24

It means microseconds, which is 1/1000th of a millisecond (1000 μs = 1 ms). The Greek letter mu (μ) is the SI prefix for micro-.

Ahh, Thanks. Here's the wikipedia link for those interested. http://en.wikipedia.org/wiki/Microsecond Is there a way to show ms for everything? – sproketboy Mar 15 '12 at 13:10
No idea about that, as I don't use JProfiler (not really a Java programmer here ;) – BoltClock Mar 15 '12 at 13:16

@DanHoward You can open the view settings (View->View settings in the menu or the corresponding tool bar button) to change the way times are displayed in JProfiler. – Ingo Kegel Mar 15 '12 at 20:18

As others have said it's 1000 times smaller than a millisecond, and is a standard measurement (not just for jprofiler.)

There's a nice table here that lists the various units, microseconds included!

Micro seconds = 1000th of a milli second
