metric (SI) units. 4.2333 mm. The pica is a typographic unit of measure corresponding to approximately 1⁄6 of an inch, or from 1⁄68 to 1⁄73 of a foot. One pica is further divided into 12 points. In printing, three pica measures are used: The French pica of 12 Didot points (also called cicero) generally is: 12 × 0.376 = 4.512 mm (0.1776 in).
Scanners and cameras. "PPI" or "pixel density" may also describe image scanner resolution. In this context, PPI is synonymous with samples per inch. In digital photography, pixel density is the number of pixels divided by the area of the sensor. A typical DSLR, circa 2013, has 1–6.2 MP/cm 2; a typical compact has 20–70 MP/cm 2.
In graphic, web design, and user interfaces, a "pixel" may refer to a fixed length rather than a true pixel on the screen to accommodate different pixel densities. A typical definition, such as in CSS, is that a "physical" pixel is 1 ⁄ 96 inch (0.26 mm). Doing so makes sure a given element will display as the same size no matter what screen ...
As it is, the Macintosh 128K featured a screen measuring 512 pixels in width by 342 pixels in height, and this corresponded to the width of standard office paper (512 px ÷ 72 px/in ≈ 7.1 in, with a 0.7 in margin down each side when assuming 8 + 1 ⁄ 2 in × 11 in North American paper size; in the rest of the world, it is 210 mm × 297 mm ...

35 mm film is scanned for release on DVD at 1080 or 2000 lines as of 2005. The actual resolution of 35 mm original camera negatives is the subject of much debate. Measured resolutions of negative film have ranged from 25–200 LP/mm, which equates to a range of 325 lines for 2-perf, to (theoretically) over 2300 lines for 4-perf shot on T-Max 100.
A lung nodule is an irregular growth in your lungs that has a diameter of less than 30 millimeters (mm), or 1.2 inches. Lung nodules are very common and are estimated to occur in 2% to 24% of the ...
