How 168 hours converts to weeks
Every time conversion goes through the second, which is the SI base unit for time. 168 hours is 604,800 seconds, and dividing that by the length of one week gives the answer.
1 week = 168 hours 168 ÷ 168 = 1
Written as a clock reading rather than a decimal, that is 7 days. The decimal form is what a form field or a spreadsheet wants; the clock form is what a schedule wants, and the two are not interchangeable.
Where 168 hours shows up
A week contains 168 hours, and working-time law carves its limits out of that total. The EU Working Time Directive caps average weekly working time at 48 hours including overtime, measured not week by week but as an average across a reference period — 17 weeks by default, extendable further under national law or a collective agreement. Set against the 168, that cap leaves 120 hours, which sounds generous until sleep alone takes roughly a third of the week.
