Calculation note
Weeks-to-hours conversion is exact when a week is treated as seven fixed 24-hour days. The useful record states that basis and keeps calendar, payroll and legal-week rules separate from pure duration arithmetic.
A fixed week has 168 hours
For unit conversion, a week is normally treated as seven 24-hour days. Multiplying 7 by 24 gives the 168-hour basis used by the calculator.
Payroll weeks can mean more than duration
A payroll week may include jurisdiction-specific overtime thresholds, paid breaks, unpaid breaks, public holidays or award rules. This page converts time units; it does not decide those rules.
Printable duration notes prevent lost context
A printed weeks-to-hours report can show the original weeks, added days, added hours, repeat count, exact hours, rounded planning value and notes. That is safer than copying only the final hour total.
