Question

One microgram of medicine corresponds to how many grams??  
A. 0.000001  
B. 0.00001  
C. 0.0001  
D. 0.001

Accepted Answer

Correct Answer: (A)0.000001. 
Rationale: One microgram corresponds to 0.000001 grams.The metric prefix "micro-" (symbol µ) denotes a factor of one-millionth, or 10⁻⁶. Therefore, one microgram (1 µg) is one-millionth of a gram. In decimal form, this is represented by moving the decimal point in 1.0 six places to the left.A) 0.000001This decimal has six digits after the decimal point (five zeros and a one), with the '1' in the sixth place. This represents 1 × 10⁻⁶, which is the correct equivalence for one microgram.B) 0.00001This number has five digits after the decimal, representing 1 × 10⁻⁵, or ten micrograms. It is ten times larger than one microgram.C) 0.0001This number has four digits after the decimal, representing 1 × 10⁻⁴, or one hundred micrograms. It is one hundred times larger than one microgram.D) 0.001This number has three digits after the decimal, representing 1 × 10⁻³ grams, which is one milligram. One milligram is one thousand times larger than one microgram.Conclusion:Metric prefixes define specific powers of ten. The prefix "micro-" is unequivocally defined as 10⁻⁶. Consequently, converting from micrograms to grams involves dividing by one million, which in decimal notation is written as 0.000001 grams.
