Microsoft Excel getting seconds elapsed in a time interval - excel

Is there a formula in excel to get the total seconds elapsed in a specific time period? For example I need to get the total seconds starting 12:00mn to 6:37am. I also have more than 2000 rows, so having the exact formula that can compute all at once would make it easier. thank you

There are a few ways to do it, the simplest one is to simply multiply the time difference by 86400 (24 hours * 60 minutes * 60 seconds).
=(EndTime-StartTime)*86400

Google Sheets: Which time format to use to display and convert hours to minutes?

I am having issues understanding which time format to use to show Over Time in minutes and hour format.
I have used "Elapsed minutes' and that worked fine, until I had to deduct the times (J column).
It gives me a number '-85860', and it should give me '480'enter image description here
You need to type the 60 in as 1:00 (one hour), otherwise it will be taken as 60 days (=86400 minutes).

Rounding error in SECOND function when converting hh:mm:ss.000 to milliseconds in Excel?

I am trying to write a function to convert a column of times entered in a [hh]:mm:ss.000 format to milliseconds using the following function:
=MINUTE(C75)*60000+SECOND(C75)*1000+RIGHT(TEXT(C75, "hh:mm:ss.000"),3)
From playing around with the numbers with a calculator, I've deduced that the problem is that the SECOND() function is rounding to the nearest second based on the milliseconds rather than copying the exact value. For example, 00:17:39.320 will convert correctly, but 00:17:39.760 will not, as the function will convert the seconds using 40 rather than 39.
Does anyone know ways around this?
Thank you!
Multiply your time by 86400000
=C75 * 86400000
Excel stores time as a fraction of a date. 12.00 noon will be .5 because its half of 24. Therefore 24 hours times 60 minutes times 60 seconds give you total seconds times 1000 milliseconds gives your desired result.

Excel formula for time

Looking for formula to determine how many of the time given between 14:00 to 22:00
enter image description here
You can subtract both datetimes and you'll get the amount of days. If you want it to be in seconds, you just need to multiply this by the amount of seconds within one day (60 seconds * 60 minutes * 24 hours), and obviously, don't forget to format your cell content as a simple number (the subtracting might cause a datetime formatting, which is not what you want).

Excel: Converting a duration (hours, minutes, seconds) to increments of 6 minutes

I have a spreadsheet column with durations of hours, minutes, and seconds. For example, 0:01:00 is 1 minute. 1:06:28 is 1 hour, 6 minutes, and 28 seconds.
I'm trying to convert this data into increments of 10% of an hour (6 minutes). So, 0:00:01 (a second) would be converted to 0.1. 0:06:00 (6 minutes) would also be 0.1. 1:12:01 (1 hour, 12 minutes and 1 second) would be 1.3.
Any ideas on how to handle this in Excel (or Google Sheets)? Thanks very much.
The formula is:
=ROUNDUP(A1*24, 1)
Intervals (time) in Excel are stored as fractions of a 24 hour day, so converting the day fraction to an hour fraction just means multiplying by 24.
=ROUNDUP(A1*24, 1) won't work in OpenOffice Calc nor in some configurations of Google Sheets and Excel, but
=ROUNDUP(A1*24;1)
will (in OpenOffice Calc and some configurations of Google Sheets and Excel).

Excel units of time conversion

I need to change a value of time from days:hours:minutes, into either hours with a decimal or minutes. My data comes up as 001:05:46 for example. I am having trouble with the leading zeros confusing excel. Any help would be great!
Assuming that your value to parse is formatted in DDD:HH:MM like 001:05:46... There are a lot of ways to do this but here's a simple one. To convert into hours we need to take the days times 24 hours per day, add the hours, and add the minutes times 1 hour per 60 minutes:
=LEFT(A1,3)*24+MID(A1,5,2)+RIGHT(A1,2)/60
To get this value in terms of minutes we multiply by 60 minutes per hour. A possible modification of the original formula to reach this point would be:
=LEFT(A1,3)*24*60+MID(A1,5,2)*60+RIGHT(A1,2)
