Clarification about grid generation units

[tm-jc-nacpil]

Hi! I'm currently using the grid generation tutorial and would like to clarify if the output grids in the example are in degrees or meters?

In the create grids section, the tutorial mentions that the units of the grids are dependent on the units of the projection.

Create a grid generator with a size of 50000. The units of the grid size are dependent on the projection of the geodataframe, in this case, EPSG:4326.

When printing out the CRS of region3_gdf, it shows that the units are in decimal degrees.

>> region3_gdf.crs  # CRS info
<Geographic 2D CRS: EPSG:4326>
Name: WGS 84
Axis Info [ellipsoidal]:
- Lat[north]: Geodetic latitude (degree)
- Lon[east]: Geodetic longitude (degree)
Area of Use:
- name: World.
- bounds: (-180.0, -90.0, 180.0, 90.0)
Datum: World Geodetic System 1984 ensemble
- Ellipsoid: WGS 84
- Prime Meridian: Greenwich

However, the output grids in the tutorial are described to be in kilometer scale:

grid_generator5k = grids.SquareGridGenerator(
    region3_gdf, 5000
)  # 5 km x 5 km square cells

Let me know also if this is the correct place for this question or if I should place this in Discussions instead. Thanks! :D
