This really drives me crazy, because i know its simple statistics.

According to the World Health Organization (WHO), a child growth of age by weight should be like this :

you dont have to go into the link, here is a screenshot of that link:

if a child age is 0 weeks (just got birth!), and if his weight is for example 2.6 KG we know that he is in the percentile 5% , if his weight is 3 KG, he is in the percentile 25%

and so on

my question is, how can i know the percentilein between?

for example, for a given weight of 3.1 KG, what is the percentile? should be between 25%-50%

How can i know? do we need extra info for that? im not sure what L M S is but i assume that L is lengh , M is median and S --> i dont know

This is not linear equation, this is how the Graph looks like:

Thank you
