India dwarfs Russia: about 3,155,807 km² km² against 16,879,701 km² km². At true size India is about 5.3× larger — the whole of Russia fits into India roughly 5 times.
India sits in Asia, Russia in Europe. On the old Mercator map the latitude gap distorted how large each felt beside the other; at true size the answer is simply 5.3×.
The old map muddied it further: Mercator inflates India about 1.2× and Russia about 6.1×, so on a Mercator-style map this pair appears 27.5× apart instead of the true 5.3×.
India fits 5× into Russia.
