First worry is always a tsunami, but in this case it seems like it only generated a max of ~20cm: https://www.tsunami.gov/events/PAAQ/2021/07/29/qwzteb/7/WEAK...

There is old joke that if you use metric when announcing a 50mm tsunami, half of Americans will run for the hills. "~20cm" could mean half a foot or 20 hundred meters depending on how much you remember from highschool. Many agencies have policies on how and where metric should be used in public announcements.

fwiw pretty much all unfamiliar americans will associate 'centi' with small, not "hundred"(eth)

Could have made the olympic surfing competitions interesting (which they moved sooner because of the storm that passed by)

The Tsunami was in Alaska, not Japan.

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.

Yes, but how many of you reflect over the nomenclature? How many of you know the actual diameter of a "twenty-two" (even if spelled out as .22)? People don't often think about the meaning behind colloquialisms.

Or 10mm if you’ve wrenched a car

In Japan, TV advisory was extra rough seas (no tsunami) on pacific side throughout the day tomorrow (Friday) as a result of this earthquake.

Here's the big Japanese tsunami that devastated Fukushima arriving in California.

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 0.22 inches in diameter. It's very slightly bigger than that. In the domain of ammunition, there is often a mismatch between actual diameter and nominal diameter.
