    So, in an on-going work frustration, I can't seem to a) get an answer, OR b) convince others that the correct units for the following *is*not*hours*

    if I record a time, say from a timer which reports hours, minutes and seconds, what are the correct units? if it is a whole hour (04:00:00) that's easy -- units are hours. for all other cases, though, what should it be: 04:20:00 is what? yes, 4 hours and 20 minutes, but if I'm writing up in a lab note book, what units should go with 04:20:00?

    You're not alone in your frustration... I've pondered (and argued) about this several times. On my tests I usually label columns thus:

    Units for the first two columns are hours:minutes:seconds. First column is time of the day, second column is elapsed test time, so the worker running the test can simply transcribe from his watch and stopwatch to the control sheet. I usually then convert to seconds and hours (columns 3 and 4), and when I write the report I just use the decimal hours. I just use one decimal for the hours so the reader won't think I'm talking about hours and minutes. Yes, I've seen people say that 3.40 hours means 3 hours 40 minutes!

    You are displaying 3 units: hours, minutes and seconds. You could include a one-time legend hh:mm:ss, but after that, you shouldn't needed to show the units since the format is clear.

    I'm not sure this helps, but it's kind of interesting.

    I found this: English notation for hour, minutes and seconds and How to write lengths of time in a short way with numbers.
