There is No Error: the problem is that 1/60 hr cannot be easily nor perfectly converted into 1/100 hr. The problem stems from the fact that if a column of time is added, it may be off. The line in the middle indicates the mid-point at which rounding moves to. Rounding occurs at the mid-point of every quarter hour, starting at the top of the hour. Rounding to 15 minutes (or 1/4 hour) observes two thresholds that indicate whether the clock-ins and clock-outs are rounded up or down The first 7.5 minutes is always rounded down while the second-half 7. The following minutes to decimal conversion chart reflects the four-quarter hour segments. The time conversion of 7:56 IN according to the Dial.Ī Time Conversion Chart is provided here to help with the converting of the time from minutes to 10ths or 100ths prior to adding it on a calculator.Ī Note About Converting to Hundredths:There has been confusion about the use of the 1/100 hours option on reports. The supervisor must approve all recorded time before the decimal rounding occurs. The Mechanical Time Recorders come with the Dial of Decimal Equivalents, which displays the conversion slightly different from how our software products round the time: The total daily hours after converting the time. Similarly, with the 20 Series Timeclocks that print in standard minutes, if an employee clocks in at 7:56 and out at 15:35, if subtracting 7:56 from 15:35, the total would display as 7.79. The total hours after converting the time. If trying to add these times together on a calculator without converting the minutes to hundredths, the total would display as 17.88. Without converting the minutes to hundredths, the caluclations can be off because an hour contains 60 minutes and regular calculations done on a calculator are displayed in units of 100.įor example, if an employee worked 9 hours, 32 minutes on one day and 8 hours, 56 minutes on another day, the totals will display on the 7000E or in Pa圜lock as 9:32 and 8:56, if the settings were not adjusted to show totals in hundredths. Calculate Total Working Hours & Minutes Calculating total hours worked is usually straightforward if you have a time-tracking system (pen-and-paper, time clock, spreadsheet, etc.) however, if your policy requires you to round employee hours to the nearest quarter, as the Department of Labor allows, it can be tricky. Additions and subtractions for time done on a calculator without converting minutes to tenths or hundredths causes confusion when verifying or calculating employee hours.
