Converting time as 7.5 (which represents 7:30 AM) to 0730

[Steve]

I have downloaded data that has 7.5 in cell G2. I used G2*100 to get 0750 in
cell I2, formatted as 0000.
To convert the .5 hour (50) to 30 as minutes, I used in J2 (right, I2,2) to
pull out the 50, and then in K2 =IF(J2="50","30",J2). This does give me the
30 I need (or the 00 for exact hour times), and then in L2 I have
=LEFT(I2,2)&K2 which gives me the correct result in cases where the number
is > or = 10. Single digits, such as 7 produce 7530 instead of 0730. It seems
like it's ignoring the zero in front of the 7 in I2, and therefore using the
2 left non-zero #'s, the 75, and the result is 7530.
G2 I2 J2 K2 L2
7.5 0750 50 30 7530 <- wrong should be 0730 (rep.7:30 AM)
21.5 2150 50 30 2130 <- correct (representing
9:30 PM)

Is there another simplier way, or a way to fix this problem. Basically I
need to convert #'s such as 7.5 to 0730.

Thanks,

Steve

=A1/24 and format as hhmm

XL stores times as fractional days, 1 = 24 hours. So one way:

Put 24 in an empty cell. Copy the cell. Select your times. Choose
Edit/Paste Special, selecting the Values and Divide radio buttons. Click
OK.

WIth the cells still selected, choose Format/Cells/Number/Custom and
enter [hh]mm in the input box. Click Ok.

Well I was hoping for something simple, but you surely can't get much
simplier than that. Thanks.
Is there a way to get that result 07:30 without the colon = 0730 ?

Thank you very much

You can just use a custom format of hhmm on the original time
