Wrong distance between two points in Geodjango

Question

I have user class:

class User(AbstractBaseUser):
    location = PointField(srid=4326)

and I calculate distance between two points in serializer this way:

obj.location.distance(request.user.location) * 100

For example I have two points:

POINT(-95.3385 29.7245)
POINT(-85.3385 29.7245)

One point is for authorized user the other is for the other user.

Serializer returns 1000 kilometers. I don't know what is latitude and longitude and it doesn't matter because in online calculators in one case it is a little bit more than 1000 km and in the other - a little bit less than 1000 km. And it is never 1000 km.

Any ideas why this is happening?
