114.5 kg1 kg = 2.2 lb
m = lb
2.Easy
kg× 1000g× 1000mg× 1000mcg0.002 g?

Practice exercise (made-up values, not clinical guidance). Convert 0.002 g to mcg: find x.

0.002 g1 g = 1 000 000 mcg
x = mcg
3.Medium
5.5976 mL? mLround to 0.1 mL

Practice exercise (made-up values, not clinical guidance). A dose calculation for an injection gives 5.5976 mL. The rule in this exercise is that volumes of 1 mL or more are rounded to the nearest tenth of a mL. What value x do you record?
