Core Conversion Formulas & Shift Metrics

• Standard Work Weeks: Work Weeks = Total Hours ÷ 40

• UK Office Work Weeks: Work Weeks = Total Hours ÷ 37.5

• Part-Time Work Weeks: Work Weeks = Total Hours ÷ 20

• Calendar Weeks: Calendar Weeks = Total Hours ÷ 168

• Share of Annual Work Year (%): Share % = (Decimal Weeks ÷ 52) × 100
