Frequently Asked Questions
How do I convert 1 hour 30 minutes to decimal?
1:30 equals 1.5 decimal hours because 30 minutes is 0.5 of an hour.
What does the 7-minute rule mean?
It rounds to the nearest quarter hour where 1-7 minutes round down and 8-14 minutes round up.
Can I type 90 minutes directly?
Yes. Smart input accepts values like 90 min and normalizes overflow automatically.
What is tenth-hour rounding?
Tenth-hour rounding converts time into 0.1-hour increments, where each 6 minutes equals 0.1 hour.
Can this calculate wages too?
Yes. Enter an hourly rate and the tool multiplies rounded decimal hours by that rate.
Does hourly rate persist between visits?
Yes. The hourly rate field is saved in local storage so you do not need to retype it.
Can I export multiple rows?
Yes. Add entries to the batch table, then export as CSV or PDF.
Is this suitable for official payroll filing?
It is a practical utility. Always confirm your final payroll output against local regulations and internal policy.
