In what units are properties measured in INSERT - TRANSFORM ?
Rotation is measured in degrees. The rest should be pixels or a 0-1 scale. Let me confirm with @martinb
The rest are clearly measured not in pixels, but in some fractions.
Those would be your 0-1 scale.
Zero to one where one is a “100%” value and 0 is none. Again though, let me confirm with @martinb
A scale of 1 is 1:1. A scale of 2 is twice the size. A scale of 0.5 is half.
A Position Х, Y in what units is measured ?
