-40°C 🤝 -40°F
- Less known 301.4375C at which F and K are the same and equal to 574.5875
- Yeah, they kinda relate 🥶.
  
  that's when it starts to get 'cold'. before that, it's just a 'little chilly'.
- You mean..
  -40°C = (-40-32)/18*10
Kelvin and Celsius are literally the same just offset by 273.15°
- Literally the same just different.
  
  Kelvin was developed from Celsius. The only difference is that 0° is based on absolute 0 (because it's logical and constant) rather than the rough freezing point of water (a vague and inconsistent reference point). Every degree change in one unit is exactly the same change in the other.
- F and C are laterally the same just offset by 32 and scaled by 5/9.
  
  Ehh, they were developed in different ways using completely different reference points
  
  Ah yes just rolls off the tongue. Totally the same as, an increment of one is equal in both.
- Theyre also not pointing guns at each other in the picture.
- Same relationship between Rankine and Fahrenheit.
  And 0 Kelvin and 0° Rankine are three same temperature.
  
  In that case I assume it would be 0 Rankine without degrees, too? Because it's an absolute unit like Kelvin.
Kelvin and Rankine are based.
What’s Ra°? Not Reamur (Re°) or Rømer (Rø°)
- I think Ra° is an alternate for Rankine
- Rankine is based? The same way pound-mol and 1000th of an inch are based?
  AT THAT POINT, WHY NOT JUST USE METRIC o_0
  I bite my thumb at Rankine, sir.
Because 0 is not a lack of temperature like the measurements. (With the exception of Kelvin)
- And Rankin, which is apparently just the Kelvin for Fahrenheit.
  
  🤢
Sounds funny but really, why would a weight or length measurement start with ≠0?? Like "size of the dick or prince Charles"?
- But that argument would go for temperature as well. Yet, here we are with the most commonly used ones having zero as wey more than the "nothing"-level.
  
  Zero comes from experience, at least in Celsius. Its semi-scientifical as water is a pretty big part of our world. For our life and all it is pretty much the turning point, isnt it? But of course it could also be 50 or so, as below is possible
Add eV there too.
0lbs ≠ 0kg in the absence of gravity.
- Wait what? Even if you're measuring mass both times?
  
  You're right, "pounds" is ambiguous.
  
  Kilograms are mass, but pounds are weight. Therefore 0 kg = 0 slug, or 0 N = 0 lbs
If only they made a meter equal a yard. I'm okay with a bigger yard. Let's do it.
