Work with dates
Turn a time into decimal hours
=A2*24How it works in Excel
- Excel stores a time as part of a day.
- Multiplying by 24 gives hours.
- Format the cell as Number.
- Multiply by 1440 for minutes.
The idea in general
A full day is 1, so 1.5 hours is a small slice of that.
What I assumed
- The time is in A2.
Check the result on your own data before relying on it.
