1 gram is equal to 1000 of which unit?

• A. milligrams
• B. micrograms
• C. grams
• D. kilograms

Answer: (A)

Understanding metric prefixes helps you compare masses quickly. The gram is the base unit for mass, and the prefix milli- means one thousandth. That means one gram contains 1000 of the smaller unit that shares the same base name, which are milligrams. So 1 g equals 1000 mg. This differs from micrograms (1 g equals 1,000,000 µg) and from kilograms (1 kg equals 1000 g), so the correct interpretation is that 1 gram is equal to 1000 milligrams.
