American surveyors sometimes used a longer chain of 100 feet (30.48 m), known as the engineer's chain or Ramsden's chain. The term chain in this case usually refers to the measuring instrument rather than a unit of length; the distances measured with such an instrument are normally measured in feet (and usually decimal fractions of a foot, not inches).

Famous quotes containing the word chain:
“Nae living man I’ll love again,
Since that my lovely knight is slain.
Wi ae lock of his yellow hair
I’ll chain my heart for evermair.”
—Unknown. The Lament of the Border Widow (l. 25–28)
