Rankine is there twice.
And it shouldn’t have degrees like Kelvin, right?
It does share a 0 with kelvin
And F and C share a -44
It’s actually -40. Not 44.
Not if it’s an absolute scale, no. And then it does actually agree on what 0 is with Kelvin too.
°R refers to the Réaumur temperature scale which goes from 0 for freezing and 80 is the boiling point.
And had the same zero as Kelvin.
Real metric supremacists be washing their hands with napalm after that handshake
I’m assuming this is because the concept of absolute zero did not exist when most of these temperature scales were defined, whereas zero distance and zero weight were easily observable
zero weight were easily observable
how?
How much water, by weight, is in an empty cup? Round to the nearest amount an average 17th century merchant could identify.
Clouds
I guess in terms of an actual weightless object… Not… But if you have 2 equal weight items, call their combined weight 1 weight unit, take one away, that’s half a weight unit, take two away, that’s zero weight units.
Clouds.
Remember kids, if it’s not metric it has nothing to do with science!
USGS uses imperial for a ton of publications. As a geographer, I had to get pretty comfortable with both standards.
Kelvin and Celsius are best buddies.

I’ve always been curious why 32 was chosen for the freezing point of water in Fahrenheit. or was there something else and did that just land at 32?
it’s kind of a mystery and i love it
Fahrenheit is actually a base-ten system, where 0° was the freezing temperature of a salt/water mixture used in laboratories in the 18th century, and 100° was supposed to be a human’s blood temperature. Another convenient perk of the fahrenheit system is that most European weather occurs inside it’s 0-100 range.
Eventually Fahrenheit saw the scientific need to know the freezing and boiling point of plain water, but instead of adjusting his system, he just found those values within his system.
The story I heard, and I don’t know if this is true or not, is that 100 isn’t just a human’s blood temperature, but specifically Mrs. Fahrenheit’s blood temperature.
I like that °C and K don’t point at eachother.
