There are 0.4 kg in 400 mg. You can convert milligrams to kilograms by dividing the number of milligrams by 1,000.
Since there are 1000 mg in 1 gram, and 1000 g in 1 kg, there are (1000 x 1000) mg in 1 kg, which is 1,000,000 mg in 1 kg. Or conversely, there are 0.000001 kg in 1 mg (that's 10-6 kg)
1000 mg = 1 g; 1000 g = 1 kg, therefore 1000 x 1000 or 1 000 000 mg/kg
400 kg = 400 000 gTo convert from kg to g, multiply by 1000.
6.73 milligrams = 6.73 × 10-6 kilograms (0.00000673 kg)
