Weight in relation to what? The Earth sits in the void of space, it is like a free falling apple.
I believe you are correct. Within the gravitational field around it, the whole Earth is in free fall and has no weight. The Earth has a mass , however.
Pretty nice table here: https://en.wikipedia.org/wiki/Metric_prefix "(...) he had the idea for the update when he saw media reports using unsanctioned prefixes for data storage such as brontobytes and hellabytes. (...)" and "The only letters that were not used for other units or other symbols were R and Q" So it seems the new prefixes are partly initiated by the exponential computer storage needs rather than scientif…
Uppercase MB is megabytes, lowercase mb is millibars. Both can go through a series of tubes, but millibars are also useful in dump trucks, to make the wheels go round and round.
Is anyone seriously using prefixes above Giga, besides for counting bytes or boasting numbers in popular science articles? In physics, in practice you either state the number in exponential notation and don't care abut it or for brevity introduce a more appropriate unit: barns (10⁻²⁸ m²) and electronvolts (10⁻¹⁹ J) in nuclear physics or solar mass (~10³⁰ kg) in astrophysics, etc.

Millibars is mbar not mb.

Technically there is a word for 10 000: "myriad". But nobody uses it like that anymore...
I've been guilty of using not only permille but also permyriad (‱) in certain work where it made sense …
