Hi there! I'm glad I was able to help you!
Assuming you meant 1,800, our vehicle technically weighs one FULL ton. However, if you were to round to the nearest thousandth, it would be about two tons.
A ton is equivalent 1,000 pounds, therefore with a vehicle weighing around 1,800 pounds, its weight is rounded to two tons, but if you want to get even more technical it's 1 full ton and 4/5ths, or 1.8!
I hope this sort of helped you to understand the question & answer a little bit better! :)
