If you can find a PT100 measuring bridge of lab quality,
This Smath document will return °C from measured Ω.
On the other hand, if you have a decent scientific calculator,
plug/code the three functions. If your Pt100 lab bridge is
transportable in the jungle ... you will have plenty °C in hand.
Web search is pure waste of time. The only valid item is the
eit90 from the BIPM [Bureau International des Poids et Mesures].
A long lecture necessary to understand that final calculator.

Enjoy/comment ... need more, please feel free.
