Italics mine, and holy crap that's a lot of metal shavings.. like multiple 55gal trash cans' worth.
several dozen is not several hundred
1 dozen = 12
55 us liquid gallons = 208,198 litres
the densities of metals are higher than that of
water ca 1 kg/l aluminum ca 2.7 kg/l steels and iron 7.5-8.5 kg/l brass 8.5-9 kg/l gold almost 20kg/l
several dozen kg is half a 55gal worth, maybe one...
EDIT for shavings:
https://www.mollet.de/info/schuettdichte-und-schuettgewicht....
iron and steel chips / shavings still are about 2 kg/l
aluminum is 200g / l
so one 55gal trash bin of aluminum shards is still about 40 something kg, four dozen.
thus for aluminum and aluminum only I stand corrected, it may be multiple trash bins.
I was also confused but could be German usage where comma and dots are swapped. The German 208,198 is the same as the English 208.198
Conversely the English 1,000,000 is 1.000.000 in German! Very confusing.
Remember Germany is still the place where you say four-and-twenty for twenty-four …
That's a weird remark to make. Lots of languages do that. And if you want to talk weird numbers, try Japanese with their 10k grouping (e.g. 100k is 10 10k, juu man, 1M is 100 100k, hyaku man, etc).
Regularly switching between four-and-twenty and twenty-four, I find it annoying and hence a slight frustration might have sipped through.
Since we're talking about numbers, in France we used to count by blocks of 20, and the usage somewhat persists to this day: so, for instance, 72 is read "sixty twelve" (60+12), 81 is read "four twenty one" (4x20+1), and 96 is read "four twenty sixteen" (4x20+16). Mind bending for the poor French learners...

If you look at the image, Antarctica has “data unavailable” - seems we still don’t know what the penguins use! /s
Well, yes. But it's mostly the Anglosphere being weird again: https://commons.m.wikimedia.org/wiki/File:DecimalSeparator.s...
I personally like to use thin spaces or apostrophes as a thousands separator, precisely to avoid the language confusion. I also try to avoid three decimals going for 2 or 4 instead, but you can't always do that, because it changes the content.

As someone from another language that does that: agreed. It gets even weirder with 124: one hundred four and twenty. Middle-endianness is silly.
One third of the world seems to use ".", the other third "," and the others decides with own rules or have own symbols. (Space, "'" and "·" and "_" in many variants).

Interestingly enough, the engine is produced by a company owned by the Rolls-Royce holding company, so in a meaningful way the British are helping the Germans produce warships. In the first half of the 20th century the British would have been prime suspects of the sabotage.
EDIT: a super devious way to do it would be with very small magnetized filings. It would be incredibly difficult to rid the engine of those, even completely disassembled.
This was a huge security screw up, you have to draw your security barrier and they left this huge asset on the wrong side of it. If only the followed Gauss's Law.
It would have been a much bigger security screwup if it was actively in service.
Just heat it.
I don’t think so. A 55gal Tran can full of metal shavings is probably several hundred lbs. 2 dozen kilograms is only about 53lbs.
