使用する際の注意点

• The use of amount for countable things is often considered incorrect, with number or quantity being preferred in those contexts. Some go further by restricting amount to immeasurable things (that is, things that one cannot put a specific quantity to, such as intangibles), and using quantity for things that can be measured. However, when referring to something uncountable but measurable, the term amount is so widespread that it is generally considered interchangeable with quantity.
