Final answer:
1,000 micrograms (mcg) is equivalent to 1 milligram (mg). This conversion is based on the fact that 1 microgram is 10^-6 grams and 1 milligram is 10^-3 grams.
Step-by-step explanation:
The student wants to convert 1,000 micrograms (mcg) to milligrams (mg). From the given information, we know that 1 microgram (μg) is equal to 10^-6 g and 1 milligram (mg) is equal to 10^-3 g. These two units can form a straight conversion since both of them are units of weight in the metric system.
We can state that 1000 μg * (1 mg / 1000 μg) = 1 mg. So, 1,000 micrograms is equal to 1 milligram.
