spliting numbers

Hi

I got list of tallest building from the link below. One table has Height column and the numbers are like this

100.3 m

200m

300 m

400.1m

How to get rid of m? I used Power Query-->Split-->Delimiter , first using Space and I got rid of some m but for numbers like this

200m

I can use Split--> From Digit to Non Digit, but for number like this

400.1m

If I used Split-->Digit to non Digit, I will get this

400      .1     m

But I want to split like this   400.1   m

What you would do? Thank you so much.
