This puzzle is a bit different to my usual puzzles. The idea came about following a discussion in the Ctc fan discord server which somehow got onto the subject of thermometers, and whether they should be in Celsius or Fahrenheit.
Ambiguous Thermometers
-
Each row, column and 3x3 box contains the digits 1-9.
Each line between cells represents a 'thermometer'.
Digits along a thermometer must increase either left to right or right to left.
The digits on each thermometer when read from left to right represent a temperature either in degrees Celsius or Fahrenheit.
No two thermometers show the same value but for every thermometer showing in °C there is another showing the same temperature in °F.
In addition some cells have been marked with the letters C, F & K representing the value in that cell.
Each letter represents the same number wherever it appears.
