American and British crochet terminology diverged in the 19th century: US names count the number of yarn-overs before inserting the hook, UK names count the total loops pulled through. Neither is wrong — but mixing them turns a beanie into a bucket. The rule of thumb: UK names are one step taller than US names for the same stitch.
Also different: US skip = UK miss, US gauge = UK tension, and US yarn over (yo) = UK yarn over hook (yoh). Hook sizes are labelled differently too — see the hook size chart.
Yes. UK double crochet (dc) = US single crochet (sc). Every UK name is one step 'higher' than the US name for the same stitch.
If it uses 'single crochet' (sc) it's US — that term doesn't exist in UK patterns. If it uses 'half treble' (htr) or 'miss' instead of 'skip', it's UK. Patterns from the US, Canada and most of Asia use US terms; UK, Ireland, Australia, New Zealand and South Africa mostly use UK terms.
No — only the names. A UK treble and a US double crochet are made with exactly the same movements.
Yes, and confusingly the UK numbers run the opposite way (smaller number = bigger hook). See the hook size chart tool.
