The formula

weeks = hours ÷ 168

That's a clean result because 336 is an exact multiple of 168.
Why the number is exact
A week is defined as exactly 7 days, and each day is exactly 24 hours, which makes a week exactly 168 hours. Dividing by 168 is therefore precise. The decimal for one hour, 0.00595238, repeats endlessly, but that's only the decimal form of the clean fraction 1/168 — the relationship between hours and weeks is exact, not approximate.
When you'll use it
Adding up total hours worked or hours spent on a long project to see how many weeks they add up to, and comparing large blocks of time against a standard work or calendar week.
