The scales will all read the same at infinity. ∞ But no one will be around to read them.

There is no temperature at which ALL FOUR scales have the same value.
To see this, try drawing the four scales as four lines on a graph. (The x-axis can be "absolute temperature", and the y-axis can be "reading on thermometer")
The F and C lines will cross at -40; meaning that -40º F represents the same temperature as -40º C.
The K and R lines will cross at 0.
The C and K lines will be _parallel_. Since they never cross, there is no temperature which has the same number in both the C and K scales.
The F and R lines are also parallel.
F and K cross at about 233.15.
The point being, there is no single point at which all four lines cross. So there is no temperature at which all four thermometers will show the same number.

F = 9/5 C + 32
if F = C (let's call it x)
x = 9/5 x + 32
-4/5 x = 32
x = -40
Kelvin and Rankine scales obviously intersect at absolute zero.

there isn't any temperature the with a similar numerical fee in all scales. kelvin is often 273 larger thancelcius. perhaps the respond on your question is infinity it is a numerical fee even though it is not defined so thats my superb wager! i cant style what it sounds like in this website out yet im particular you will locate it on the information superhighway

C and K can never be the same.
