Formula Explanation
Decimal Hours = Hours + (Minutes ÷ 60)
With seconds: Decimal Hours = Hours + (Minutes ÷ 60) + (Seconds ÷ 3600)
Decimal Minutes = (Hours × 60) + Minutes
With seconds: Decimal Minutes = (Hours × 60) + Minutes + (Seconds ÷ 60)
Reverse: Total Minutes = Decimal Hours × 60
Full Hours = floor(Total Minutes ÷ 60)
Remaining Minutes = Total Minutes mod 60
Example: 7 hours 45 minutes = 7 + (45 ÷ 60) = 7.75 hours.
The exact result is shown before any rounded value. Rounded decimal hours are labelled clearly.
