How to convert longtiud/latitude coordinate to X/Y coordinate to download a map in streetmap using Qgis?

[MutebAlotaibi]

I have an area in google map which I know what is its coordinate Lon/Lat but the canvas border in Qgis is defined on X/Y based to download a mapstreet map? I tried many time using this website  https://epsg.io/transform#s_srs=4326&t_srs=2318&x=21.4150000&y=39.9100000)  to convert my coordinates however the coordinates that been generated does not work with Qgis?

any help please to solve this problem?

QGIS would be better asked on their preferred Stack site
