Area of one pixel = 0.2 mm * 0.2 mm = 0.04 mm²
So “pixel value in mm²” could mean: pixel value mm2
value per pixel is vital for accurate scientific analysis, such as measuring the size of an annotation area in microscopy. Area of one pixel = 0
mm², or square millimeters, is a unit of area in the metric system. It's used to measure the size of two-dimensional objects or spaces. In medical imaging, for example, mm² might be used to quantify the area of a tumor or a specific organ. or square millimeters
