How to express the unit of measurement "ton" in China?
Is there any foreign word for "ton" in China? Is our "ton" the same as "metric ton"?
So which one of tone and (US) ton can represent China's unit of measurement "ton"?

ton
Metric ton is a unit of metric system, which is adopted in China. Therefore, we Chinese usually refer to "ton" as "metric ton". We can regard "ton" as the abbreviation of "metric ton"
1 ton / metric ton = 1000 kg
In Britain and the United States, "ton" is not the same
Kg / ton = 1000 metric tons
1 ton = 1016 kg (UK) or 907.2 kg (US)
So the English we learn is ton,
Because the original expression of 1 metric ton in English is "ton" or "metric ton", because there are too many people who use metric tons and people like to be lazy, they often abbreviate "metric ton" to "ton". So when foreigners say "ton", they may refer to "metric ton" or "ton" in their own country, but when we Chinese say "ton", we actually mean "ton"
In our country, 1 ton = 1 ton
In the United Kingdom and the United States, one metric ton is close to but not equal to one ton
