When browsing the web and documentation I see the abbreviation lon and lng used for the longitude part of geometry.
I was wondering if there is any difference between lng and lon.

2no difference because there is no standard global naming convention.– CaptDragonMay 3, 2012 at 16:46

Might switch to use "lon" from using "lng", the latter I used for long time but personally I think lon is better abbr form.– ray80sDec 23, 2013 at 8:45

While I understand that this is sort of an answer to OP's Question, it can be improved by providing supporting information on why lon is better than lng.– Devdatta TengsheDec 23, 2013 at 14:17

I think lng abbreviation is not wrong, it is a personal choice but it may cause a mixup in the words in the GIS World because The Longitude is settled in our language abbreviation of "Long" or "Lon".
You can see in wikipedia its defined as follows:
The Longitude (abbreviation: Long., λ, or lambda) of a point on the Earth's surface is the angle east or west from a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses (often improperly called great circles), which converge at the north and south poles.
from Acronyms and Abbreviations :
lon - longitude
Abbreviation: lon
Definition: longitude - also long , L , long. and LL

5The problem with abbreviation "Long" is that it is a reserved word in almost all database systems (ex. Oracle, MSAccess etc.) thus the popular variants lon and lng. May 4, 2012 at 14:11

LatLng is often used in the android community as short form of "latitude and longitude". So I think lng is not wrong. reference: developer.android.com/reference/androidx/car/cluster/navigation/… Jan 27, 2020 at 14:19
I'm pretty sure there is no difference, it's just that there are inconsistencies in the way that Longitude is abbreviated. I'm not aware if there are any resources available that are trying to set a standard for abbreviations.
Which abbreviation to use is mainly a matter of preference. Personally, I use "lat" and "lon". Here's why:
Both are 3 letters, which provides a nice symmetry. Both are phonic abbreviations that correspond to what people call them when speaking. "long" is a reserved word in most programming languages and it is harder to textually search. "lng" looks garbled.
