The SI system (International System of Units) is better than the USCS (United States Customary System) in scientific work due to its universal acceptance and standardization, which facilitates clear communication and collaboration among scientists globally. The SI system is based on coherent units derived from fundamental constants, making it more logical and easier to use for calculations and conversions. Additionally, its decimal-based structure simplifies mental arithmetic and data representation, reducing the risk of errors in scientific measurements.
A tonne is metric, Ton is imperial. One tonne is 1 000 kilograms. There are two different "tons", in North America a ton is 907 kilograms, in the UK a ton is 1 016 kilograms. This is why SI is always better, a tonne is the same wherever you are.
