Formulas for calculating time

Convert period to seconds

\(\displaystyle t_{sec} = Sec + Min× 60 + hours × 3600 + days ×86400 \)

Calculate percentage

\(\displaystyle P_{t[sec]} = \frac{t_{sec} × P}{100} \)

Example: 40% of 2 days, 8 hours and 30 minutes

\(\displaystyle t_{PW} = \frac{(2×86400) +(8×3600)+(30× 60) × 40}{100} \)

\(\displaystyle \;\;\;\; = \frac{172800+28800+ 1800× 40}{100}=81360 \;Sec \)
