How about 10^17 == "tenset", 10^27 == "venset", ...
Inspired by French vingt, from Old French vint, from Latin vīgintī.
Since the length of words (should) correspond to the frequency of usage, longer variants would be ok if not preferable too:
10^… == tento…
10^16 == tento-seize …
- decade
- century
- decagon
- centimeter
- decimal system
- decathlon
- centipede
edit: admittedly, hecto is pretty rare and centi is often used for both 1/100 and 100
> Centipedes (from New Latin centi-, "hundred", and Latin pes, pedis, "foot")
Hectolitres are commonly used in the food and drink industry. For example wineries and breweries typically measure their production in hectolitres.
Not exactly hecto but land, especially farm land is often measured in hectares. It is a non-SI metric unit equivalent to the square hectometer or 10000 square meters. We most likely kept the name because "hectare" sounds better than "square hectometer". As expected, 1 hectare is worth 100 ares, but ares and its other multiples are much less used than hectares.
2471 acres per hectare.
That may be in large part because of the unit prefixes we use. That is we think of these things in 3 orders of magnitudes because our unit prefixes come in three orders of magnitude but not the other way around. I think a much likelier explanation is the fact that many European languages (most importantly French and English) stop naming each decimal order after a thousand. If there was a word for ten-thousand—say fiorthom—but not a hundred-thousand (ten-fiorthom), surely these prefixes would map be multiples of 10⁴ as well.
... Or milliard, or giga
On paper, there are much larger units too, but they are never used.
10^6 is the same length as "mega".
10^9 is the same length as "giga".
Why is length suddenly an argument against new prefixes?
(A bit confusing since most sources list electron mass as 9x10^-31 kilograms, rather than 9x10^-28 grams.)
I think this is a error by nature.com, and Earth weighs around 5.97 ronnagram
The earth's mass may well be 5.97 ronnagrams.
The weight of the earth would be measured in newtons, yes?
The Earth has a mass, however.
The prefixes ronna and quetta represent 10^27 and 10^30, and ronto and quecto signify 10^−27 and 10^−30. Earth weighs around one ronnagram, and an electron’s mass is about one quectogram.
This is the first update to the prefix system since 1991, when the organization added zetta (10^21), zepto (10^−21), yotta (10^24) and yocto (10^−24).
