Dots Per Inch - Proposed Metrification

Proposed Metrification

See also: dots per centimetre

There is some ongoing efforts to abandon DPI in favour of metrication, giving the inter-dot spacing in dots per centimetre (dpcm) or micrometres (µm). A resolution of 72 DPI for example equals a resolution of about 28 dpcm or an inter-dot spacing of about 350 µm.

Famous quotes containing the word proposed:

    “The structure was designed by an old sea captain who believed that the world would end in a flood. He built a home in the traditional shape of the Ark, inverted, with the roof forming the hull of the proposed vessel. The builder expected that the deluge would cause the house to topple and then reverse itself, floating away on its roof until it should land on some new Ararat.”
    —For the State of New Jersey, U.S. public relief program (1935-1943)
