Flat vs. apartment, lift vs. elevator — same thing, completely different word.
What you'll learn
Beyond spelling and grammar, American and British English simply chose different everyday words for a long list of ordinary things — housing, transport, food, and clothing among them. None of these differences is difficult to learn; they're a vocabulary list to build over time, the same way you'd learn any set of synonyms.
Where you live and how you get around are two areas with especially well-known differences.
Everyday food words and words for taking time off work also diverge in familiar ways.
Most vocabulary differences are simply two different words for the same thing — but 'pants' is a real false friend, because the SAME word means two DIFFERENT things depending on the variety. In American English, 'pants' means trousers; in British English, 'pants' means underwear. Wearing the wrong assumption here can genuinely cause an embarrassing misunderstanding, so it's worth remembering on its own.
'Pants' is a genuine false friend: American 'trousers,' British 'underwear.' When in doubt, 'trousers' is understood everywhere.
Neither word is more 'correct' or more 'real' — they're regional standards, and both are fully understood by fluent speakers.
"I told my British coworker I loved her pants, and she looked so confused!"
"Oh no — in British English that means underwear! You probably meant her trousers."
"I had no idea that word could mean two totally different things."
"It's the one everyone warns you about — most other differences are just synonyms, but that one can genuinely embarrass you."
