High 10 models of measurement within the Gadget Grasp scale

The thought was provoked by a narrative in regards to the Flex Energy Modules’ 80A BMR510 (pictured). A degree-of-load converter energy stage that’s sugar-cube-sized…
Let’s name them GM models within the official-unofficial Gadget Grasp Scale*. In fact, half models are allowed, however not in frequent utilization.
Issues are sized as…
1 GM Human hair (natch, however not thatch; only one. Nothing is thinner and smaller than a human hair, until its half-a-human hair…)
2 GM Grapefruit pip (with because of our Technical Editor for a calibration be aware – “Footprint-wise, one grapefruit pip is roughly 10-15 the-size-of-Wales, though one pip has infinitely extra quantity.”)
3 GM Sugar dice (Bluebottle not included – makes me consider horses and old school cafes)
4 GM Matchbox (acquainted, however much less generally seen these days as smoking falls from favour)
5 GM Palm-sized (sufficiently big to know however not outspanning an open hand)
6 GM Pocket-sized (a sartorially-based technical definition)
7 GM Boxing ring (as within the LightSail 2 spacecraft)
8 GM Whale (singular)
9 GM Soccer pitch (for instance, a DRAM fab “the scale of 20 soccer fields”, i.e. 180 GM)
10 GM Wales (singular, a particular nation that’s distinctively sized as a unit of measurement)
Any options for what ought to come subsequent? Australia? The entire of Planet Earth itself? Share your ideas…
*To keep away from any confusion, capitalisation of GM signifies Gadget Grasp scale, with the lower-case gm representing the unrelated unit of weight, the gram, which is one thousandth of a kilogram.
