Example Calculations
Work Week Calculation
Scenario: Calculate hours in a standard 40-hour work week
Full week: 1 week = 168 hours (total)
Work week: 40 hours ÷ 168 hours = 0.238 weeks
Business days: 5 days × 8 hours = 40 hours/week
Project Planning Example
Project duration: 6 weeks
Total hours: 6 × 168 = 1,008 hours
Working hours: 6 weeks × 40 hrs = 240 hours (5-day work week)
Daily allocation: 240 hrs ÷ 30 days = 8 hours/day
Training Program Example
Training duration: 3 weeks
Total hours available: 3 × 168 = 504 hours
Training hours: 3 weeks × 30 hrs/week = 90 hours
Self-study time: 504 - 90 = 414 hours remaining

Conversion Mathematics
Weeks × 168 = Hours
Hours ÷ 168 = Weeks
Breakdown:
• 1 week = 7 days
• 1 day = 24 hours
• Therefore: 7 × 24 = 168 hours per week
Business hours calculation:
• Standard work week = 40 hours (5 days × 8 hours)
• Overtime starts at >40 hours/week
Important Note: This calculator uses total hours (168/week). For business planning, remember that a standard work week is only 40 hours.

Frequently Asked Questions
How many hours are in a standard work week?
A standard full-time work week in the United States is 40 hours, typically spread across 5 days (Monday to Friday) at 8 hours per day. However, a complete week contains 168 hours total (7 days × 24 hours). The difference between 40 working hours and 168 total hours includes evenings, nights, and weekends.
Why is understanding weeks to hours conversion important for project management?
Converting weeks to hours helps project managers create more accurate schedules, allocate resources efficiently, and estimate project costs. It allows for detailed task breakdown and helps identify potential bottlenecks. For example, knowing that a 2-week sprint equals 80 working hours (or 336 total hours) enables better team capacity planning.
How do I calculate billable hours for freelance work?
To calculate billable hours from weekly contracts, multiply the number of weeks by your expected working hours per week (usually 40 for full-time). For example, a 3-week project at 40 hours/week equals 120 billable hours. If you charge $50/hour, the total project cost would be $6,000. Always clarify whether the contract refers to working hours or total elapsed time.
What's the difference between total hours and working hours?
Total hours in a week = 168 hours (7 days × 24 hours). Working hours typically refer to business hours only, usually 40 hours/week for full-time employees (8 hours/day × 5 days). When planning projects, it's crucial to distinguish between these two: use total hours for deadline calculations and working hours for resource and cost planning.
How many weeks are in common time periods?
Here are some common conversions:
- • 1 month (30 days) ≈ 4.29 weeks = 720 hours
- • 1 quarter (3 months) ≈ 13 weeks = 2,184 hours
- • 1 year = 52.14 weeks = 8,760 hours
- • 1 academic semester (15 weeks) = 2,520 hours
- • 1 business quarter (13 weeks) = 520 working hours
