How to transform milliseconds into seconds .?

Question

I have to transform my Stopwatch "Variable" into seconds ?

Stopwatch czasAlg = new Stopwatch(); 
czasAlg.Start();
//Do semothing
czasAlg.Stop();
Decimal Tn = czasAlg.ElapsedMilliseconds/(decimal)n;

Seriously.. you don't know how to transform milliseconds into seconds? :o — ThiefMaster, Nov 14 '10 at 19:36

Divide by 1000 or use

czasAlg.Elapsed.TotalSeconds

Without your own constants and magic numbers:

TimeSpan.FromMilliseconds(x).TotalSeconds

What is the difference of .Seconds and .TotalSeconds on TimeSpan? – Erik Bergstedt Mar 13 '18 at 15:07

`.Seconds` gets the seconds place of the TimeSpan. So if it was 1 minute and 30 seconds you would get `30` back where `.TotalSeconds` would return `90`. – HackSlash Oct 20 '22 at 21:12
Use TimeSpan.Duration() to get the absolute value of the timespan. `TimeSpan.FromMilliseconds(x).Duration().TotalSeconds` – Paul Nakitare Jan 08 '23 at 20:22

Just to be different:

Multiply by 0.001.

Hm, evil idea: `double.Parse(string.Format("{0}e-3", czasAlg.ElapsedMilliseconds))` – Joey Nov 14 '10 at 20:24

How about 1s = 1000ms

Instead of using math and multiplying/diving like this: seconds (60) * 1000 = 60000, use TimeSpan instead, it's using bit operations, and due to it has a minimum cost of performance.

Milliseconds to seconds

int sixtyThousandsMillisecondsInSeconds = (int)TimeSpan.FromMilliseconds(60000).TotalSeconds;
// Outputs 60

Seconds to milliseconds

// 1 min (60 seconds) in milliseconds = 60000 (i.e 60 * 1000)
int sixtySecondsInMilliseconds = (int)TimeSpan.FromSeconds(60).TotalMilliseconds;
// Outputs 60000

Using LINQPad

int sixtyThousendsMillisecondsInSeconds = (int)TimeSpan.FromMilliseconds(60000).TotalSeconds;
sixtyThousendsMillisecondsInSeconds.Dump();

int sixtySecondsInMilliseconds = (int)TimeSpan.FromSeconds(60).TotalMilliseconds;
sixtySecondsInMilliseconds.Dump();

Results

60

60000
