How to multiply each number in a column of cells when the data is mixed with other text

Hi there forum!

I am having this problem for quite a bit.
I have the product inventory of a Chinese company and I am asked to translate the information to English, together with converting all the measurements into the American style (from centimeters into inches, kilograms into pounds)
It would be much easier if the data was better organized but the best I could do to work it out looks like this: Size: L122 * W90 * H106cm
There is more than a hundred of these so its not efficient at all for me to do the measurements one by one.
How can I create a formula to do the measurements for me?
I have attached a sample spreadsheet on this post so you can take a look at it. Any help is highly appreciated.

Cheers,

Orkun

I would make 3 columns, L, W, H to separate the values:
L2 = MID(A1,2,FIND(" ",A1,2)-1)
W2 =MID($A1,FIND("W",$A1,2)+1,FIND(" ",$A1,1)-2)
etc.
Then convert the values in another cell to English units.

Thanks but that still makes it hard in some cases. Is there any way to multiply numbers in a column when they are mixed with letters? I mean teach Excel just to consider numbers in a function and nothing else
