Convert all number abbreviations to numeric values in a text file

I'd like to convert all number abbreviations such as 1K, 100K, 1M, etc. in a text file into plain numeric values such as 1000, 100000, 1000000, etc.

So for example, if I have the following text file:

1.3K apples  87.9K oranges  156K mangos  541.7K carrots  1.8M potatoes  

I would like to convert it to the following in bash:

1300 apples  87900 oranges  156000 mangos  541700 carrots  1800000 potatoes  

The command I have used is to replace matching strings of number abbreviations with their full numeric values like so:

sed -e 's/1K/1000/g' -e 's/1M/1000000/g' text-file.txt  

My problem is that I cannot find and replace ALL of the possible number abbreviations when variation occurs. I'd like to do this until at least up to one decimal abbreviations.
