We must first understand the conversion relationship between tons, kilograms and kilograms; The relationships among 1 kg, 1 kg and 1 kg can be expressed by the following mathematical formula: 1 t = 1000 kg, 1 kg =2 kg,1t =/kloc.

Combining these two formulas, we can get the following conversion relationship: 1.5 ton =1.5×1000 =1500 kg; 1.5 ton = 1.5×2× 1000=3000 kg.
