Points and picas are units used to measure type as they allow for smaller increments than fractions of inches, with 1 point equaling 1/72 of an inch and 1 pica equaling 12 points. Common abbreviations include points as pts and picas as p, and conversions include 1 pica and 6 points equalling 1 pica + 6 points and 18 points equalling 0.25 inches.

1. 1 Point = 1/72 inch
1 Pica = 12 Points
1 Inch = 6 Picas
designers use Points and Picas to measure type because these are very small
increments which are way easier to notate than long fractions in inches.

2. NAME NOTATION
points = pts
picas = p
1p6 = 1 pica + 6 points =
18 pts = .25 inch
