# Convert the given time into milliseconds using Java

I [am trying](https://answers.mindstick.com/qa/36834/which-two-programming-languages-should-i-master-in-if-i-am-trying-to-get-into-google-or-facebook) to [convert](https://www.mindstick.com/forum/2093/configurationmanager-appsettings-convert-n-to-n-why) the time (hh:mm:ss) into milliseconds. How could i do it?

Is it [right](https://www.mindstick.com/articles/12766/check-whether-you-are-doing-digital-transformation-right-or-not) to use the following one?

hh * mm * ss * 1000;

But if the minute is 00 or [second](https://answers.mindstick.com/qa/41761/how-did-the-second-industrial-revolution-influence-women-s-roles-in-society) is 00, it gives 0.

How do I calculate this?

You Should use this code: - **(hh * 3600 + mm * 60 + ss) * 1000;**
