Amount vs. Number: What’s The Difference?

If you stop and think for a second, amount and number seem like they are pretty similar, right? Even native English-speakers have confused words like these. They are similar but they have a key difference in English grammar. The word number refers to something that can be counted or a “countable noun”; whereas the word amount is used for things that can’t be counted, or an “uncountable noun” that usually refers to a large amount or a large quantity of something. 


  • Amount: non-count noun/mass noun
    1. It takes an immense amount of energy to wake up with two toddlers. 
    2. I thought that my life was going perfectly but things can get in the way a good amount of the time.
  • Number: countable noun
    1. Can you count the number of people as they enter the conference room for me?
    2. Believe it or not, my dog can count to 5.
