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?

Reinold

Also worth noting that ns is nano-second or 1/1000th of a μs. e.g. System.nanoTime() – Manzanilla

Answer 1

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. en.wikipedia.org/wiki/Microsecond Is there a way to show ms for everything? – Reinold

No idea about that, as I don't use JProfiler (not really a Java programmer here ;) – Masoretic

@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. – Wandering

Answer 2

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!

Answer 3

Micro seconds = 1000th of a milli second
