Understanding the Conversion Process
Converting hours to weeks depends on which week format you're using. The standard calendar week contains 168 hours, while work weeks vary by country and industry standards.
Hours to Weeks Formula
Standard Week Formula:
Weeks = Hours ÷ 168
To convert hours to weeks using a standard calendar week, divide the total hours by 168. This is because one full week contains 7 days × 24 hours = 168 hours.
Example: 336 hours ÷ 168 = 2 weeks
Work Week Formula
For a 40-hour work week: Weeks = Hours ÷ 40
For a 35-hour work week: Weeks = Hours ÷ 35
The formula changes based on your specific work schedule definition.
