D2 = A3 * 24 * 60 * 60
Function syntax: = CONVERT (number, from_unit, to_unit)
Inside:
The value of the unit:
For the above example, the default from_unit value is "day" , and if you want to change to hours / minutes / seconds then change to_unit to "hr" / "mn" / "sec" respectively. And you collect the same way as above.
Another way to change hours to minutes, seconds; You can use the functions HOUR, MINUTE, SECOND to calculate the number of hours and minutes and use the sum calculation.
Function syntax:
= HOUR (serial_number)
= MINUTE (serial_number)
= SECOND (serial_number)
Where: serial_number is the number to be converted.
For the above example, you type the formula in turn as follows:
B2 = HOUR (A2)
C2 = MINUTE (A2)
D2 = SECOND (A2)
You copy the formula to the remaining lines in the cell to get the result:
To calculate the total number of minutes in column E, the formula will equal the number of hours * 24 + minutes + seconds / 60.
In cell E2 = B2 * 60 + C2 + D2 / 60. Copy the formula for the remaining rows in the column. You get the following result:
Good luck!
