terminology - Difference between lon and lng

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.

Answer

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.
