How do i change the "text weight based shipping"

Thank for the great plugin….
I want to calculate shipping charges based on no of products.

For eg:

1. 1-5 products – X amount
2. 6-10 products – 2X amount
3. ……..
4. ……..
5. 21-25 products

5X amount\

So i assigned every item the same weight .1 kg

Then used your plugin for range of .1-.5 kg

Now on cart page shipping method appears as weight based shipping. I want to change the text to some thing else… How do i change it…

Thanks in advance
