Those two adjectives (description words) are basically the same. It really depends on the context. Large generally means a lot. It more often refers to quantity. Huge means really a lot and more often refers something relative to size, but not always Examples: huge cow (overly big cow), huge amount of work (I always have a lot of work, that is normal for me. If I have more than a lot, then I his huge.), a large car is one that is big, a huge truck refers to the fact that trucks are already big but this one is REALLY big, Example of being relative to what you are comparing - This dragonfly is huge. (In comparison to other dragonflies, it is overly big. The word this implies the comparison to other dragonflies.) You would never say, dragonflies are huge. (Comparing dragonflies to other things, it is not not huge, compared to everything.

There's actually no real difference between "huge quantities" and "large quantities". Both phrases mean you have a lot of something. The only difference is that if you use the word "huge", you place more emphasis on the fact that you have a lot of something. "Large" is a more neutral sounding word.

700,000,000! hahaha its a matter of relative magnitude - huge difference might be an order of magnitude larger than large - nanoseconds and microseconds are large and huge differences in a competitive online share-trading application 老鬼
