Try this example →US survey chain (chUS). The US survey chain is 66 US survey feet, about 20.1168 m.
Typographic point (pt). A typographic point is 1/72 of an inch (about 0.3528 mm), used for font sizes.
There are 57,024.1 typographic points in one US survey chain.
Multiply the number of US survey chains by 57,024.1. For example, 10 US survey chains equal 570,241 typographic points.
One typographic point equals 1.75364 × 10⁻⁵ US survey chains.
684,289 typographic points. Other common values: 5 US survey chains = 285,121 typographic points and 100 US survey chains = 5,702,410 typographic points.
