Below is a table of crochet terms in both U.S. terminology & U.K. terminology. The main way to tell if a pattern is an American pattern or not, is if the pattern says single crochet (sc). The British and European systems do not use sc as an abbreviation.
|U.S. Abbreviation||U.K. Abbreviation|
|single crochet (sc)||double crochet (dc)|
|half-double crochet (hdc)||half-treble crochet (htr)|
|double crochet (dc)||treble crochet (tr)|
|treble crochet (tr)||double treble crochet (dtr)|
|double treble (dtr)||triple treble (tr tr)|
|triple treble (tr tr)||quadruple treble (qtr)|
