GPS reference points

[Segilla]

From a letter about my uncle killed WW1 in 1917:-

He was buried by his comrades at a point N.W. of Havrincourt. The map reference which may be useful to you later is K.15d.95.80.

Does a GPS device use the same system?

Right, I understand now.
I think a better idea of the precise location would come from the war diary for the action / regiment concerned.
However the wkipedia entry on Havrincourt suggests the motorway has obliterated the site of the 1917 action:

"I think a better idea of the precise location would come from the war diary for the action / regiment concerned."

Or maybe from the precise British trench map coordinates (K15d.95.80) provided by the comrades who buried him, those coordinates equate to about 50.126164,3.083982 in modern day coordinates, which is about 450Meters North East of the motorway services.

E-communication isn't the best way to convey tone, so I will choose to ignore what I perceive as unwarranted rudeness from Chuck.
Just to suggest: why would the regiment's war diaries not give additional information to a location?
The place where the deceased was temporarily buried was one part of a larger battlefield, providing the context for what happened.

Great work AB...

Mosaic, I wasn't being rude, but a lot of the answers on this thread seem to show that people have, either not read, or not understood the question. the details in the OP narrow the location down to a 5yard square where the gentleman in question was buried, yet the majority of answers have been directing the OP to a random location on the other side of the town in question.

With Aberrents excellent overlaid map the modern day coordinates recognisable by a sat nav would be:

50.125627, 3.085247
or
+50° 7' 32.26", +3° 5' 6.89"

Many thanks for all the information.
I was fortunate not only to be sent a copy of the letter to WJEM's family after his death pinpionting his original burial place but also finding some relevant notes about Havrincourt Communal Cemetery, 'from which four British soldiers were taken to Achiet-le-Grand Communal Cemetery Extension and three to Flesquières.
