Libya dwarfs United States: about 1,626,369 km² km² against 9,439,424 km² km². At true size Libya is about 5.8× larger — the whole of United States fits into Libya roughly 5 times.
Libya sits in Africa, United States in North America. On the old Mercator map the latitude gap distorted how large each felt beside the other; at true size the answer is simply 5.8×.
The old map muddied it further: Mercator inflates Libya about 1.3× and United States about 2×, so on a Mercator-style map this pair appears 9.1× apart instead of the true 5.8×.
Libya fits 5× into United States.
