What is the converted unit equivalent to 0.001 grams?

To determine the correct unit equivalent to 0.001 grams, it's important to understand the metric system and how different units are scaled in terms of grams.

A milligram is defined as one-thousandth of a gram (1 mg = 0.001 g). Therefore, when you have 0.001 grams, you can express this amount directly in milligrams, resulting in 1 milligram. This is why the conversion leads to the conclusion that the equivalent is 1 milligram.

In contrast, other options represent different metric prefixes:

• A microgram (1 µg) is one-millionth of a gram (0.000001 g), which is much smaller than 0.001 grams.

• A centigram (1 cg) is one-hundredth of a gram (0.01 g), which is larger than 0.001 grams.

• A decigram (1 dg) is one-tenth of a gram (0.1 g), which is also larger than 0.001 grams.

Using this understanding of metric prefixes and their relationships with grams clarifies that the correct unit conversion for 0.001 grams is indeed 1 milligram.
