It takes 38.6× United Kingdom to fill People's Republic of China.

The United Kingdom fits inside China about 39 times over. China spans a continent's
worth of terrain from the Pacific to the Himalayas; the whole UK is barely a fortieth of
it.
The numbers
- China: 9,394,396 km²
- United Kingdom: 243,280 km²
9,394,396 ÷ 243,280 = 38.6, so about 39 UKs fit inside China.
Why the map hides it
The ratio is projection-proof — 39 is 39 on any map. But Mercator works against your
intuition here: the UK sits far north, around 54°, where the map inflates it noticeably,
while China sits lower and is stretched less. So the UK looks relatively larger than it
really is, and the true thirty-nine-to-one gap is bigger than the drawn sizes suggest.
Asked as how many Englands or how many Great Britains fit in China, the answer is the
same — the United Kingdom is the whole island group of England, Scotland, Wales and
Northern Ireland.
