When filling out a timesheet for your work hours, you might find your company requires all working hours to be marked in tenths of an hour. This means you must write "8.8" instead of 8 3/4 hours, for example. Calculating time in tenths is quite straightforward and can be easily memorized if necessary. When converting to tenths, you are basically taking the number of minutes past the hour and turning it into a decimal point.
Work out the exact number of hours and minutes worked on your shift. For example, 8 hours 20 minutes.
Convert the number of minutes to a decimal point. The conversions are as follows -- 1-6 minutes becomes .1, 7-12 becomes .2, 13-18 becomes .3, 19-24 becomes .4, 25-30 becomes .5, 31-36 becomes .6, 37-42 becomes .7, 43-48 becomes .8, 49-54 becomes .9 and minutes 55 to 59 are rounded up to the next hour, becoming .0.
Mark your timesheet with the decimal version of your work hours. Our example becomes "8.4" because 20 minutes falls in the ".4" portion of the hour. An 8 hour, 56 minute shift is rounded up to 9 hours and marked as "9.0."
