I am new to working on spatial data. Someone sent me a series of coordinates x,y in meters of particular locations in London. Here is an example:
|X (m)||Y (m)|
The person was able to plot these coordinates in QGIS.
I was expecting the coordinates to be longitude and latitude which I thought were measured in degrees. I'm also mindful that these coordinates could still be used in QGIS.
Can you clarify this for me and explain how I could actually change the coordinate system in QGIS from degrees to meters?
