Pixels Map Length to Addresses

Pixels Cover Field

field length per pixel

Pixel size is the calibrated field length divided by pixel count. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

The image field has a checked length

The field length is 12 m.

Pixel size comes from field length over pixels

With 6 equal pixels, each pixel covers 2 m.
