Time conversions are exact down to the day and approximate above it. Seconds, minutes, hours and days have fixed ratios, but a month has no fixed length and a year has two — 365 days in the calendar and 365.25 in the astronomical convention used here. For anything with legal or contractual weight, count the actual calendar dates rather than converting a duration, because the difference accumulates precisely where it is least welcome.
weeks to hours formula
To go the other way, use week = hour ÷ 168.
About these units
The seven-day week has no astronomical basis at all. It is the one unit of time inherited purely by cultural continuity, and it is remarkably consistent worldwide.
The hour is 3,600 seconds. Its length is arbitrary in physical terms: it descends from dividing daylight into twelve parts, which meant the hour changed with the seasons until mechanical clocks fixed it.
Week is also written weeks and wks. Hour is also written hours, hr and hrs.
