o D. 20,000 mg
o Rationale: There are 1,000 mg in 1 g. Therefore, 2 g x 1,000 =
2,000 mg.
• 2. Convert 0.5 L to milliliters.
o A. 50 mL
o B. 500 mL
o C. 5,000 mL
o D. 0.05 mL
o Rationale: There are 1,000 mL in 1 L. Therefore, 0.5 L x 1,000 =
500 mL.
• 3. How many micrograms are in 0.25 mg?
o A. 2.5 mcg
o B. 25 mcg
, o C. 250 mcg

o Rationale: There are 1,000 mcg in 1 mg. Therefore, 0.25 mg x
1,000 = 250 mcg.
• 4. Convert 1.5 kg to grams.
o A. 150 g
o B. 1,500 g
o C. 15,000 g
o D. 0.0015 g
o Rationale: There are 1,000 g in 1 kg. Therefore, 1.5 kg x 1,000 =
1,500 g.
• 5. How many milliliters are in 3 teaspoons?
o A. 5 mL
o B. 10 mL
o C. 15 mL

o Rationale: 1 teaspoon (tsp) = 5 mL. Therefore, 3 tsp x 5 mL = 15
mL.
• 6. Convert 30 mL to tablespoons.
o A. 1 tbsp
o B. 2 tbsp
o C. 3 tbsp
o D. 6 tbsp
, o Rationale: 1 tablespoon (tbsp) = 15 mL. Therefore, 30 mL / 15 mL
= 2 tbsp.

• 9. How many grams are in 500 mg?
o A. 0.5 g
o B. 5 g
o C. 50 g
o D. 0.05 g
o Rationale: There are 1,000 mg in 1 g. Therefore, 500 mg / 1,000 =
0.5 g.
• 10. Convert 4,000 mL to liters.
o A. 0.4 L
, o B. 4 L
o C. 40 L
o D. 400 L
