1 gram is equal to how many micrograms?

One gram is equal to 1,000,000 micrograms because the metric system is based on decimal multiples. Specifically, 1 gram is defined as 1,000 milligrams, and each milligram is equal to 1,000 micrograms.

By multiplying these conversions together, we find that:

1 gram = 1,000 milligrams × 1,000 micrograms/milligram = 1,000,000 micrograms.

This shows the direct relationship between grams and micrograms, confirming that 1 gram indeed translates to 1 million micrograms. Therefore, the provided answer aligns perfectly with the metric system's conversion rules.
