The quick rule for your head
Multiply feet by 30 and add half a centimetre per foot: 6 ft × 30 = 180, plus 3 ≈ 183 cm (exact: 182.9). For feet-and-inches heights, convert the whole thing to inches and multiply by 2.54 — the half-step through inches avoids the classic error of typing 5.6 for 5 ft 6 in, which is actually 5 ft 7.2 in.
Where this conversion shows up
The reverse of the height lookup: an American 'five-eleven' needs to become 180 cm for a European form, a basketball roster, or a visa application. It also appears in real estate and DIY, where US room dimensions and lumber lengths in feet must match metric floor plans.
