First let’s talk about Pixels (px). Displayed on a digital device, it is smallest unit of measurement in an image, or to say, a graphic. It is also known as Picture element. A picture, text, video, an artwork have pixels combined together to make it. 1pixel is equals to 0.352777778 millimeter and a 100 pixel is equals to 1.0416666666666667 inches when in 96 DPI or dots-per-inch.
Now, the second unit, which is Inches (in). What is an inch? It is one-twelfth of a foot. An inch in centimeters is 2.54, while in millimeters it is 25.4 in 60 dots-per-inch or DPI.
Next is Centimeters or cm, a metric unit equal to one-hundredth of a meter. 1 centimeter is equal to 28 pixels in 72 DPI.
Further, lets take Millimeters or mm. It is unit of measurement which is equal to 0ne-thousandth of a meter. Converted into pixel it is 3.779528.
Point or pt is used to measure the length of a font, leading or any item on a page. It is another smallest unit of measurement, which is equals to 1/72 of an inch or 0.353 mm. In 96 DPI, a point when converted into pixel is 1.3333333333333333. Point is used for designing.
Finally, the Picas (pc). Used to represent fixed horizontal and column width, it is less than 1/6 of an inch and 1/72 of a foot. It is mostly used to design newspapers, journals, ads, magazines and newsletters. 1 pica is equals to 16 pixels.
