under 1 US gal

[Haroon]

Marhaba;
in the following sentence from Wiki:
Container types are metal, glass, paper, plastic or a combination under 1 US gal (3.79 L).
I could not understand what (Under) mean here. Any help appreciated

حجمها اقل من...

I guess سعة is better for things you can think of as containers and حجم is better for more solid things?
