Get nearest places with the comparison of longitude and latitude in MySQL

I am trying to get nearest places nearby me using following query.

select 
    user_address_id,
    round( 
      ( 6371* acos( least(1.0,  
        cos( radians(19.024808088594966) ) 
        * cos( radians(latitude) ) 
        * cos( radians(longitude) - radians(72.84048742388586) ) 
        + sin( radians(19.024808088594966) ) 
        * sin( radians(latitude) 
      ) ) ) 
    ), 1) as distance
from 
    user_address 

This query works but giving difference of almost 1.5 km instead of actual. I mean if I am at point A and I want distance up to point B. Then if actual distance between point A and B is 2.0 Km but then by using above query it returns me only 0.5 Km.

Please help me in this query to get actual distance between other places and me.

Thanks in advance.
