If we collect 1,080,000 chestnuts per hectare and each c heat it weighs 2.65g how many kilograms of chestnuts are produced per hectare

In order to come to the result as to how much kg of chestnuts are produced per hectare we need to do two things.

First, we need to multiply the weight of each chestnut by the amount of chestnuts:

1,080,000 x 2.65 = 2,862,000

So we have 2,862,000 grams of chestnuts per hectare. Now, to see how much kg of chestnuts are there we just need to convert the grams in kg:

1 g = 0.001 kg

Now we need to multiply the number of grams of chestnuts to 0.001:

2,862,000 x 0.001 = 2,862

We got 2,862 kg of chestnuts per hectare.
