Canadian friends, you use all kinds of units. Are you able to convert all of them or is the weight of a human a total different scale to you than a horse or a pack if flour? #units #imperialSystem #SIUnits

Attorney implies rney; therefore picorney, microrney, desi-, hecto-, kilo-, megarney etc.

The British have much to answer for. On behalf of our colonial ancestors, we apologise profusely. I dream of a homogeneous metricated future... #SIUnits

Imperial units are famously baffling.

For while most of the world operates with the metric system and its easily understandable measurements based on the number ten, the USA, Liberia, Myanmar, and (partially) the United Kingdom still use an older, more confusing system.

Wer hätte damit gerechnet? Es gibt neue SI-Präfixe.
siehe hier: https://www.npl.co.uk/si-prefix

in Kürze:
Ronna (Symbol R) für 10²⁷
Quetta (Symbol Q) für 10³⁰

und
ronto (Symbol r) für 10⁻²⁷
quecto (Symbol q) für 10⁻³⁰

Faszinierend!

The Earth weighs about six ronnagram, Jupiter about two quettagram and the diameter of the observable universe is about one ronnametre. Those are the new SI prefixes representing ronna (10^27) and quetta (10^30).

At the other end you have the ronto (10^-27) and quecto (10^-30). A ronto is useful for expressing the flux density of a radio emission (Jansky) which is 10^-26 Watts Metre^-2 Hertz^-1.

The Earth now weighs 6 ronnagrams. What does that mean? Find out in this news story from the Washington Post https://wapo.st/3XgZMX5 :-)

The luminosity of the LHC is 100 am⁻²s⁻¹.

#siunits are not always useful. But 10³⁴cm⁻²s⁻¹ is not much better.

The electron mass is 0.9 rontogram.

Now you know it. #siunits

Is this ronna-bonkers?
