This is why I say ‘metre’ for the measure and ‘meter’ for the measurement device

In the same way a US ton and a metric ton is like 10% different, a 556 bullet is actually 5.7 mm across.

I would make a bet that more mass shootings are done with 9mm. Depending on which shootings they consider ‘mass’ I see estimates from 60-80% for handgun usage. I’m sure the cheap .22 is a large number, but 9mm is probably right up there. There is a large bias in reporting the school shootings and shootings involving rifles by the media. They almost ignore the others.

As a cold weathered folk, I can confirm that 70 is my upper limit for nice temperature

I’d adjust it to 68/20 just so it lines up with whole numbers in both systems. And on second thought, make it 90 per degree Fahrenheit so any whole F or C value can convert to a whole number.

it needs to be a range, you can’t really just have a single point, something like 50f to 70f would be good. Some people like a little below, some people like a little above, the 60s are generally pretty comfy all around though.

We also need to consider clothing as well. Which i do in this case.
