Convert up to 500 time durations between hours:minutes and decimal hours. Get a total, check each row and export the conversion table as CSV.
Formula and assumptions
Decimal hours = whole hours + minutes ÷ 60. In reverse, multiply decimal hours by 60 and round to the nearest minute for hours:minutes display. Sum original values before rounding the total.
A colon separates hours from minutes, which use a base of 60. A decimal point expresses a fraction of an hour. Use 7:45 for seven hours and forty-five minutes in the first mode, or 7.75 in decimal mode. The converter rejects invalid minute portions such as 7:75 instead of silently treating them as another format.
Reconcile rounding before uploading
Use the downloadable table to compare each source value with its converted value. Decimal rows display four places, while hours:minutes displays whole minutes. Totals are calculated from original inputs. An external payroll system may use a different rounding policy, so compare its import specification before using a rounded display as a final record.
Frequently asked questions
What is 7 hours 45 minutes in decimal hours?
7 + 45 ÷ 60 = 7.75 hours. It is not 7.45 hours.
Can I paste multiple rows?
Yes. Paste one duration per line, without headers, names or currency symbols. Select the format that matches every row. The current limit is 500 rows.
Why can the displayed rows differ slightly from the total?
Each displayed row may be rounded. The total adds the original values before rounding, avoiding accumulated display rounding.
Does conversion round clock punches?
No. It converts durations. It does not apply a nearest-quarter-hour rule to employee clock-in or clock-out times.
Convert Minutes and Excel Times to Decimal Hours — Divide a number of minutes by 60. For an Excel cell containing a genuine time duration stored as a fraction of a day, multiply its value by 24.
Why Decimal Hours Totals Differ After Rounding — Rounding each timesheet row can produce a different total from adding the original durations and rounding once. Compare the two methods before investigating missing time.
