How do I convert ticks to minutes?

TimeSpan.FromTicks(28000000000).TotalMinutes;

A single tick represents one hundred nanoseconds or one ten-millionth of a second. FROM MSDN.

So 28 000 000 000 * 1/10 000 000 = 2 800 sec. 2 800 sec /60 = 46.6666min

Or you can do it programmaticly with TimeSpan:

    static void Main()
    {
        TimeSpan ts = TimeSpan.FromTicks(28000000000);
        double minutesFromTs = ts.TotalMinutes;
        Console.WriteLine(minutesFromTs);
        Console.Read();
    }

Both give me 46 min and not 480 min...

You can do this way :

TimeSpan duration = new TimeSpan(tickCount)
double minutes = duration.TotalMinutes;

The clearest way in my view is to use TimeSpan.FromTicks and then convert that to minutes:

TimeSpan ts = TimeSpan.FromTicks(ticks);
double minutes = ts.TotalMinutes;

there are 600 million ticks per minute. ticksperminute

TimeSpan.FromTicks( 28000000000 ).TotalMinutes;
