Typographic point (pt). A typographic point is 1/72 of an inch (about 0.3528 mm), used for font sizes.
Chain (ch). A chain is 66 feet (20.1168 m), a surveying unit; 80 chains make one mile.
There are 1.75365 × 10⁻⁵ chains in one typographic point.
Multiply the number of typographic points by 1.75365 × 10⁻⁵. For example, 10 typographic points equal 0.000175365 chains.
One chain equals 57,024 typographic points.
0.0175365 chains. Other common values: 100 typographic points = 0.00175365 chains and 10,000 typographic points = 0.175365 chains.
