Answer:

$410mg/day *\frac{1000 ug}{1 mg}$

Recommended daily Amount (RDA) of magnesium is 410,000 μg/day.

Explanation:

There are 1000μg in 1 mg and 1000 mg in 1g

1 mg=1000μg

The Recommended daily Amount (RDA) is 410 mg/day of magnesium. Converting 410 mg/day into μg/day

$410mg/day *\frac{1000 ug}{1 mg}$

It will become 410,000 μg/day

So Recommended daily Amount (RDA) of magnesium is 410,000 μg/day.
