# Convert hours and minutes to military time for billing

I need  convert theses time to military time and then rounded up or down to the nearest quarter hour for billing purpose. I usually  just estimate and round up and down as I see fit up or down.  I have calculated actual minutes.  In column E I need a formula that will Rounded up or down to the closest Quarter Hour for billing.  I may not have the best formula in Column D and E.  I manually rounded F and not sure if I have fairly rounded that column. I always go back and forth.  So now I trying to find a fair rounding factor in Military time and a formula to calculate the time. Column F is my end Goal. Then I can add up the column for Total Hours and used that amount to bill Clients.

Hi,

First of all, the converted to military time in column E can be computed as:

=D2*24

Format this column as Number.  This can be used for the Roundup/Rounddown

=MROUND(E2,0.25)

Hope this helps.
