6.4 kg= 6400 g 600000 mg = 600 g
600000mg< 640g< 6.4 kg

After converting all weights to grams, the order from least to greatest is 600 g (600,000 mg) < 640 g < 6400 g (6.4 kg). By converting all units to grams, we can easily compare their values. This shows that 600 g is the smallest and 6400 g is the largest weight.
