How to calculate distance between two PointField?
<p>I use Postgis with Django to store geographic points. I have a model like the following:</p>

<pre><code>from django.contrib.gis.db import models
class Event(models.Model)
    position = models.PointField()
</code></pre>

<p>I have two events(ev1, ev2). Here is the position value of each:</p>

<pre><code>SRID=4326;POINT (-73.6335140000000052 45.5472019999999986)
SRID=4326;POINT (-73.6267909999999972 45.5459189999999978)
</code></pre>

<p>My goal is to get distance in meters between those two points. If i do:</p>

<pre><code>ev1.position.distance(ev2.position)
</code></pre>

<p>I get <code>0.006844327432269004
</code>
How can I convert this value in meters?</p>

<p>Thanks!</p>
