No clue how to get proper values for the thermistors.

Hihi! haven’t been here in quite a while.
Anyway, I’ve got a problem. I cannot seem to figure out the proper values for the thermistors in my 3D printer.
I have spent a few hours researching, and found I need a Beta Value and an R value. I know the thermistors are 100kOhms. (according to Reddit, https://www.reddit.com/r/3Dprinting/comments/5ozkvi/does_anyone_know_what_thermistors_come_in_the/ ) And according to Marlin Firmware tables for said thermistor, it has these values:

Using the values of
“M305 P0 T100000 R1000 B4200 ; Set thermistor + ADC parameters for heater 0
M143 H0 S120 ; Set temperature limit for heater 0 to 120C
results in tempature readings of 38C when it should be roughly 22C
Hopefully I phrased this in a way thats not as confusing as it is to me.
Any help is appreciated.
Thanks!
