A <Pt100> has nominal <electrical resistance> $100\,\Omega$ at $0\,{}^\circ\mathrm C$.<Mercury Thermometer Alternatives: Platinum Resistance Thermometers (PRTs) by National Institute of Standards and Technology>[Platinum Resistance Thermometers, opening explanation: conventional 100-ohm element at 0 °C]{ref} Here $0\,{}^\circ\mathrm C$ is the reference for the nominal element designation; it is distinct from the $0.01\,{}^\circ\mathrm C$ water <triple point> used in <SPRT> calibration. The following <Pt100 local linear model> deliberately stipulates one approximate response for calculations.
