Enter the two parts of a shift
Use the separate hour and minute boxes when a paper timesheet already splits a duration into two columns. Enter eight in Hours and thirty in Minutes to get 8.50 hours. The minute box is a count of minutes, not the digits after a decimal point. Entering thirty minutes therefore adds half an hour rather than three tenths of an hour.
Both fields accept non-negative whole numbers. If only one field has an entry, the other field is treated as zero. Clearing both fields gives an empty result instead of a calculated zero. Type an explicit zero when the shift really has no duration. This distinction helps you spot records you have not entered yet.
Carry extra minutes into hours
The minute field can exceed fifty-nine. Entering one hour and ninety minutes gives two hours and thirty minutes, which is 2.50 decimal hours. Likewise, eight hours and seventy-five minutes becomes 9.25. A normalization notice makes the carry visible, so the tool accepts a legitimate accumulated minute total without silently changing its meaning.
Long durations do not wrap after a day. A project total of twenty-five hours and thirty minutes remains 25.50 hours. These inputs describe elapsed time, not a clock position. To include seconds, switch to the single-field format and enter h:mm:ss. A malformed or negative value shows an error and disables copying until corrected.
Choose the displayed precision
Two decimal places are convenient for many work logs, but they cannot represent every minute exactly. Eight hours and one minute displays as 8.02 at two places, 8.0167 at four places, and 8.016667 at six places. Each display comes from the same underlying duration of 28,860 seconds. Changing the precision does not change that duration.
Do not add already-rounded values when preparing a combined record. Three one-minute tasks display as 0.02 each, while their exact total is 0.05 hours. Use the Batch tab or the seven-day tool to combine source durations first. That workflow keeps tiny rounding differences from accumulating into a larger discrepancy.
Move the value into a work record
Copy transfers the current displayed number, with its selected decimal places. The clipboard action confirms success on the button. Clear removes the fields and disables copying. Undo clear restores your previous entries. Always check the destination column format: a decimal result belongs in a numeric hours column rather than a clock-time column.
This tool does not compute clock-in to clock-out differences or deduct breaks. Enter the actual net duration you intend to convert. It also does not determine whether time qualifies for overtime. Use the separate federal or California estimate after checking the relevant workweek and regular hourly rate. Those estimates explain their own legal scope and limitations.
Review the destination record
Before pasting, check the unit expected by the destination field. A field labeled minutes should receive a minute count rather than decimal hours. A field labeled hours may expect either a decimal or a separate minute entry. Keep a source copy of the original duration so that a later reviewer can reproduce the conversion. For a numerical cross-check, the example 8:30 contains 510 minutes and 30,600 seconds.
