Hours to Minutes

[JimS]

How to I turn 1:17 into minutes?

Also, how would I divide 1:17 by 20 (minutes)?

What you need to know is that Excel store time as a fraction of a day
So to convert 1:17 to minuets use =A1*24*60
To divide by 20: =A1*24*60/20 or =A1*24*3

With 1:17 in A1,
To return minutes:

=A1*1440

And to divide by 20:

=A1*1440/20

You can do this with a custom format.

XL2003:

The custom format to use is '[m]' (without the quotes).

Note that formatting changes the appearance without affecting your
underlying value. SO, it will not affect time mathematics.

OR multiply the value:

=A1*24*60 (note 24 hours in a day, 60 minutes in an hours)
This increases the value to a decimal.

OR use a combination

=--TEXT(B5,"[m]") - the double negative changes a string to a number.
This also increases the value to a decimal.


Division is straightforward:

If A1 has 1:17 and A2 has 0:20 then A1/A2 = 3.85

You may need to format the answer to a number to see the above result.


This should help you understand time calculations:
