# Resistance vs. Temperature Tables

The condensed Resistance VS Temperature Tables on the following pages are provided to aid in the proper RTD element selection.

Notice that the tables for the various platinum curves are for the standard 100 ohm @ 0°C sensor.

To calculate the resistance of:

50 ohm, multiply the values by .5;
200 ohm, multiply the values by 2;
500 ohm, multiply the values by 5;
1000 ohm, multiply the values by 10.

Table C100 for the 100 ohm @ 25°C Copper (90.35 ohms @ 0°C) is published. To calculate the resistance of the 10 ohm at 25°C (9.035 ohms @ 0°C) multiply the value shown by .1.
