As a healthcare professional, you have to convert patient weights, fluid volumes, medication weights, and more. Conversion math isn’t hard to do as long as you know the basic conversion factors. Here are the most useful ones:
Converting lb to kg and kg to lb
lb = kg × 2.2
kg = lb ÷ 2.2
Converting mL to L and L to mL
mL = L × 1,000
L = mL ÷ 1,000
Converting mg to g, g to mg, mg to mcg, and mcg to mg
mg = g × 1,000
g = mg ÷ 1,000
mcg = mg × 1,000
mg = mcg ÷ 1,000
