Both are the unit of mass.
1 short ton = 2000 pounds
1 short ton = 907.18474 kg
Thus, 3.72 short ton = [tex] 907.18474 kg \times 3.72 [/tex]
= 3,374.727 kg
Now, convert kg to mg:
1 kg = 10,00,000 mg
Therefore,
3.72 short tons = [tex] 3,374.727 kg \times 10,00,000 [/tex]
= [tex] 3.3747 \times 10^{9} mg [/tex]
Hence, 3.72 short tons = [tex] 3.3747 \times 10^{9} mg [/tex]
