Quickly convert time to seconds/minutes/hours in Excel

Kutools for Excel

For example we have a time data in Cell A1, such as 11:10:03 AM. Normally we can convert the time to seconds with applying formula =A1*86400 (or convert to minutes with formula =A1*1440, or convert to hours with formula =A1*24), and then format the formula cell as General or Number. Kutools for Excel's Convert Time utility can simplify the operation, and help you convert a mass of HH:MM:SS formatting data to seconds/minutes/hours in Excel with only one click.
