📊 UNDERSTANDING DECIMAL TIME

Decimal Hours: Expresses time as a fraction of an hour. 30 minutes = 0.5 hours. 15 minutes = 0.25 hours. 45 minutes = 0.75 hours.
Common Timesheet Examples: 7:30 = 7.50 | 8:15 = 8.25 | 6:45 = 6.75 | 9:20 = 9.333
Why Decimal Time? Most payroll systems, invoicing platforms, and timesheets store time in decimal format because it's easier to multiply by hourly rates without unit conversion.
Decimal Days: 1 day = 24 hours. 0.5 days = 12 hours. Useful in project management and resource scheduling.

⚡ CONVERSION FORMULAS

Decimal Hours → H:M:S: Hours = floor(decimal). Minutes = floor((decimal − hours) × 60). Seconds = round(((decimal − hours) × 60 − minutes) × 60).
H:M:S → Decimal Hours: Decimal = hours + (minutes ÷ 60) + (seconds ÷ 3600).
Decimal Minutes → H:M:S: Convert to seconds first: total seconds = decimal × 60. Then extract H, M, S.
Pay Estimate: Gross Pay = Decimal Hours × Hourly Rate. (When input is minutes or seconds, convert to hours first.)
Decimal Days → H:M:S: Total seconds = decimal × 86400. Extract H, M, S from total seconds.
