Quantity/quantities

Quantity means the amount of something, so when do we use it in plural form?
Can you give me some examples?

Many thanks :slight_smile:

These pills come in two quantities: 100 in the small bottle and 500 in the large bottle.

You use it in the plural form when you have more than one amount of something to consider:

When ordering, note down the sizes, colours, and quantities required of each item.

If taken in large quantities, the drug can result in liver failure. <-- Note: Here the meaning is several ‘large quantities’ taken over more than one time, rather than ‘a large quantity’ taken at one time.

In “Use equantities of nuts and raisins in the cake”, does the plural mean ‘equantities of nuts and raisins’ used more than one time?
How to understand the plural ‘quantities’ in “quantities of food was spread out on the table”?

‘equantities’ is not a word. You appear to mean ‘equal quantities’.

This means the same amount of nuts as raisins. If you use 100g of nuts you have to use 100g of raisins, etc.

Why does it used the plural

1 quantity of nuts, 1 quantity of fruit - that makes 2. 2 is plural.
