Small, medium, and large are contextual. If you lack sufficient context to use such classifiers then objective terms can be used - &#x27;[a heap of] 200g of wheat&#x27;.<p>Personally I&#x27;d classify &quot;any quantity of discrete articles in which are least one article is held up from contact with the ground&#x2F;container as being a heap&quot;. Heaps are haphazard stacks to me; ergo 2+ items constitute a heap when they are arranged appropriately.<p>A heap of grain is no longer a heap when spread across furrows (but may be lots of little heaps!).<p>It&#x27;s like temperature, a volume of stuff being hot is variable 1K is hot on some circumstances, 10E3 Kelvin if cold in others but we have absolute scales to work around such issues.
