NTC and Beta

NTC Thermistor Calculator

Use this calculator to compute the Beta value, temperature, or resistance for an NTC thermistor.

1️⃣ Calculate Beta Value

Enter resistance at two known temperatures.

Resistance at T1 (R1):
Ω kΩ
Temperature T1 (°C):

Resistance at T2 (R2):
Ω kΩ
Temperature T2 (°C):

2️⃣ Calculate Temperature or Resistance

Enter Beta value and any one of resistance or temperature.

Beta (β):

Reference Resistance (R₀ at 25°C):
Ω kΩ
Resistance (R):
Ω kΩ
Temperature (°C):
