Re: [libreoffice-users] Calc airithmetic snafu

Greetings,

If you do not like adding columns, you could do the following:

1) Select everything (CTRL-A)
2) Do a search & replace to remove all the "km" indications. This
should also convert the entry in the cells to numbers at the same time.
3) Keeping what is still selected, go to Cell > Format (CTRL-1), and
set the number format to User defined with the format as # ##0.0" km".
This will have your numbers displayed with the proper units.

I hope this helps.
Rémy.
