Why Convert Weeks to Hours?

Converting between weeks (wk) and hours (h) is one of the most common time conversions. Whether for engineering, cooking, travel, or science, knowing how to quickly convert wk to h saves time and prevents errors.

Time conversion between wk and h is essential for project management, astronomy, and high-speed electronics. While day-to-day scheduling is simple, scientific and engineering fields often require converting between vast timescales (millennia) and infinitesimal ones (nanoseconds). Video editors and audio engineers work with frames and samples that require precise time unit conversions to sync media perfectly. In logistics, accurate delivery estimates depend on converting travel durations across time zones and varying speed metrics. Miscalculating time units can lead to missed deadlines, data desynchronization, or navigation errors in GPS systems.

How to Convert Weeks to Hours

To convert weeks to hours, use the following formula:

h = wk × 168

Example: 1 wk = 168 h

For example, 5 wk = 840 h, 10 wk = 1680 h, and 100 wk = 16800 h. For larger values, 1000 wk = 168000 h. Conversely, 1 h = 0.005952380952 wk. Our calculator above performs this conversion instantly with full precision — no rounding errors.

Common Mistakes to Avoid

Decimal time: thinking 1.50 hours is 1 hour 50 minutes (it's 1 hour 30 minutes).
Leap years: assuming every year has 365 days.
Month length: assuming all months are 30 days.

Pro Tips

Excel format: Be careful converting time in Excel; it stores dates as serial numbers.
Time zones: Always specify UTC offset when scheduling international calls.
Seconds in day: There are 86,400 seconds in a standard day.

What is a Week?

A unit of time equal to 7 days.

Standard cycle for work and rest.

What is a Hour?

The hour (h) is a unit of time equal to 60 minutes or 3,600 seconds. Historically defined as 1/24 of a day.

Hours are the standard unit for work shifts, travel duration, and daily scheduling worldwide.
