Distance between 2 points in V3

[Mikoto]

Hello, i can't find any method in documentation for calculating the
distance between 2 points (with latlng).
Is such method exists in v3 or I should use v2 api?

You should use direction service http://code.google.com/intl/it-IT/apis/maps/documentation/v3/services.html#Directions

It's not exactly what i was looking for. I want to calculate distance between two point in straight line, and i could not find anything in the doc.

You can search on google for the Haversine formula. You can find a javascript implementation in this ruler for google maps v.3:

This formula is pretty accurate for calculating distance between two
points. Accuracy will vary by region so do some research to fine tune
it for your target area.

distance = Math.sqrt((69.1*(cy-lat))*(69.1*(cy-lat))+(53.0*(cx-lng))*
(53.0*(cx-lng)));
