What is the Difference Between "If" and "In case"?

As conjunctions, in case and if are normally used in different ways. In case is commonly used to talk about things we do in order to prepare for what might happen in the future; If is used to express what we will do in a given situation in the future.  

  • Have your pistol ready in case we should need it.
  • Don't wait up for me in case I should be late. 
  • Let's buy another blanket in case Ces comes.
  • If you are not trained to use an extinguisher, don't try.
  • If they fire, have no compunction about shooting them down.
  • I can stand this strain no longer; I shall go mad if it continues.

Meanwhile, in case of is a prepositional phrase with a wider meaning than in case. If can be used in the same sense or in similar situations as in case of. Check out below examples:

  • In case of fire, follow the company's fire response procedures. (If there is a fire...) 
  • Stock your kitchen in case of disaster. (..if disaster occurs/happens.)
  • In case of fatality or other critical injury, contact the police and ambulance services immediately. (If fatality or other critical injury occurs...)
