Double-Decker Buses
Modern equivalent
12,000 kilograms (12 Tonnes)
A classic, quirky British media benchmark answering the common question of how heavy a standard London bus is.
An empty standard London double-decker bus weighs approximately 12 tonnes (12,000 kg or around 26,455 lbs). Frequently deployed by British journalists, science popularisers, and public agencies, this framework provides a humorous and instantly recognisable mental benchmark for massive weights like bridge loads, whales, or cargo ships.
