That depends on the type of bus in question. As buses vary all over the world - with double-decker or single, long or short, the only "international standard" I can think of is the well-known London Routemaster bus, the ones with the open platform at the back. They weigh 7.6 tonnes that equates to 8.377566 US tons (short ton) or 7.4799696 UK tons (long ton) Therefore 40,000 tones would require either 5,348 or 4,775 buses.
