My area lies between E 92.25-92.50 and N 24.50-24.75. When I tried to draw the coordinates on QGIS 3.8 map composer, it showed the co ordinates as E 8.00-E 24.000 and N 0.000-16.000. I used the correct coordinates and projections but the problem still persists. I took "Decimal with suffix" and used "cm" or "mm" as the interval units. But that should not be a problem because the layer and the project are in the same projections. Please show with illustration how to fix this problem. QGIS grid outines are attached.
