If you were speaking of a solar power installation you would say, for example, a 300 MW installation -- honoring Watt. Why, then, a M8.2 earthquake? Why not a 8.2 R earthquake to honor Richter?
Because the magnitude is no longer defined using the original Richter scale. Earthquake magnitudes are now defined using a similar scale called the moment magnitude scale.
Also watts are an SI unit of power, whereas Richters are not a unit of earthquake. It's just the name for the scale itself.
American public schools have been using metric for decades. Science classes in American public schools use metric exclusively since the 80s at least. When you meet an American who makes a big deal out of not knowing what a meter is, 9 times out of 10 they're putting on a performative patriotic display mean to get a rise out of you. That, or they're quite elderly. Incidentally, .22 LR is nominally but not actually 0.2…
With calibers there is a difference between american .22 and european .22. As I understand it, the american measurement is slightly larger as it includes a bit of the rifling groves whereas the European standard was only the bullet width. So the same bullet measures slightly larger on the american scale. Or I might have that backwards, one of the two is different. https://www.rifleshootermag.com/editorial/comparing-a…
From what I understand, ".22 LR" is nominally .22 inches, actually is .223 inches, and is labeled as 5.6x15mmR in Europe while actually being something like 5.66mm (the 'x15' is the length of the case in millimeters, and the R means rimmed.) They are called different things and both are not quite their nominal sizes, but I think they're interchangeable in practice.

Speaking of Watts, is there any way to translate the magnitude M for an earthquake into an equivalent MW of energy?
Time so see what Dutchsinse, the earthquake maverick says about this. https://m.youtube.com/watch?v=hhfLTDA8I9g
Pretty interesting, especially when he shows the buoys on the east cost that registered the quake & the plate overlay to show why they felt the quake (because they were on the the other edge of the plate).
Kind of amazing he he managed to put up a 1hr+ video so soon after the quake, ~1.5 hours or so.
Also a bit confusing why the comment posting this video is (as of my comment) getting downvoted? Is this youtuber not considered credible on the topic?

Wow. I wonder if any local news station has ever said, "That earthquake with an epicenter in Whittier was a 4.5 on the moment magnitude scale."

Don't they usually say "It was a magnitude 4.5 quake?"

> Speaking of Watts, is there any way to translate the magnitude M for an earthquake into an equivalent MW of energy?
No, because while if other parameters are the same moment magnitude is logarithmic in energy, the other parameters differ between real earthquakes.
Seeing the unusual strength of this one, it'll be interesting to see if there's a "quake-walk" around the 'ring of fire' like the clockwise one a few years back.
You see, they're all connected to the same body of water. And if the tsunami was directional towards the Japanese coast it would've caused issues there.
I think we all know that.
I just don't see how this had anything to do with typhoons and surf contests in Japan, seemed silly.
