Dip: device independent pixels (device independent pixel ). different devices have different display effects, which are related to the hardware of the device. We recommend that you use this function to support WVGA, HVGA, and QVGA without pixels.
Dp: dip is the same

Pt: point, a standard unit of length, 1pt = 1/72 inch, used in the printing industry, very easy to use;
Sp: scaled pixels (zoom in pixels). It is mainly used to display the best for textsize in fonts.
In (INCHES): the unit of length.
Mm (mm): the unit of length.

Px = dip * density/160, when the screen density is 160 (Medium), px = dip
