Given that the recommended daily allowance of the trace metal magnesium is 410mg/day for males, this quantity when expressed in μg/day would be this: 410mg x 1000 μg would be 410000 μg/day <span>4.1x<span>10^5 </span></span>μg/day. Hope this is the answer that you are looking for. Have a great day!
