How to Replace Text in One Column Completely?

Hi everyone!

I have a small problem of efficiency and I hope you can help.

We get orders for our products in feet and the format is something like this 2' X 3'. Sometimes it is really wild like 7'-6" X 9'-6" (feet)

We have to convert the sizes to cm for our suppliers, so we manually change 2' X 3' to 60 x 90 (cm).

I have a list of the corresponding sizes, so I know that 2'-3" X 10' is supposed to be sent as 70 x 300

I want to make the process of this conversion faster. There are a lot of different sizes, but they are always in a single column, somewhat like so:

Is there something I can do to automate this text replacement?

Thanks!
