Frequently asked questions
Is 1.5 hours the same as 1:50?
No. 1.5 hours equals 1 hour 30 minutes; the digits after a decimal are fractions of 60 minutes.
Why do totals differ after rounding?
Rounding each item before summing can differ from rounding the final total.
Can I use results for payroll?
Confirm the employer’s official timekeeping and rounding rules first.
