A number (often 0–255) representing how bright or dark that spot is. In a CT scan, this might represent tissue density (Hounsfield Units). Spatial Value ( mm2m m squared pixel value mm2

The farmer knows exactly how many square meters of crop need to be sprayed. Spatial Value ( mm2m m squared A standard
: Once you know the size of a pixel in millimeters, you can calculate its area in mm² by squaring the pixel size. Using the example above, a pixel size of 0.1 mm translates to an area of 0.1 mm * 0.1 mm = 0.01 mm² per pixel.
