Hi everyone,
I want to ask the following question but I can't figure out the right choice, the answer of the question is in millions of tonnes

how much potato is harvested each year? 20 tonnes
or
how many potatoes are harvested each year? 20 tonnes

And which sentence would be correct suppose I wanted to talk about a line graph

The given line graph provides information about how much potato is harvested in millions of tonnes
or
The given line graph provides information about how many potatoes are harvested in millions of tonnes

This is rather a tricky one. While "potato" (uncountable) is fine to describe the food ("Would you like some potato"), as a commodity it always seems to be a countable noun. In a shop, I would ask for "five kilos of potatoes". Only "How many potatoes are harvested?" sounds natural to me, even though the expected answer is in tonnes. I would also use "how many potatoes" in the second sentence.

I don't think the question works with potatoes.

You need something like "What amount of potatoes are harvested every year?"

"How many tonnes of potatoes..."

In BE, that is -- I've never heard an AE speaker say that.

I agree with Cenzontle, though I would measure the amount in tons.

But we employ "amount" for non-count nouns only, I don't think it can be used with potatoes..

"How many tonnes of potatoes..."
but what if we don't know the answer, I mean what if we don't know if the answer is 500 kg or 1 tonne or 2 tonnes?

It makes sense. I suppose there's not much we can do about it, so I think I will go with your recommendation. Thank you!

"How big is the potato harvest?"
1 ton = 2,000 lb.
1 tonne = 1,000 kg. (2,200 lb.).

"How big is the potato harvest?"
1 ton = 2,000 lb.
1 tonne = 1,000 kg. (2,200 lb.).
That just went over my head.
So is it possible to ask, "How big is the potato harvest? "
If the answer is yes, then I think we have a worthy candidate. It makes sense!

Yes, and "the graph provides information about the size of the potato harvest..."
