Convert Picas (pc) to Millimetres (mm)

The pica is a unit of length in the field of typography and uses the symbol pc.

There are 12 points in 1 pica. On computers 1 pica is exactly 1/6 of an inch (about 4.23 mm).

Picas are expressed using numbers and a lower case p on software such as Adobe InDesign - for example 8p6 which would represent 8 picas and 6 points (or 8.5 picas).

The Pica is very useful in measuring and calculating the space needed to print letters and words on paper - for example when laying out books or magazine articles; the font lengths are quantified by the number of characters per pica (cpp).

The millimetre (American spelling millimeter) is a unit of length and is a multiple of the SI unit metre. It uses the symbol mm.

There are 1000 mm in 1 m and 10 mm in 1 cm. From this one can derive that there are 0.03937 in.

The millimetre is sometimes verbally abbreviated to 'mil' - which can cause confusion in the US as there is a unit there that means thousandth of an inch.
