Common Conversion Factors in Medical Dosage Calculations

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
