About this Table
Full Type N Thermocouple Table from −270 to 1300 °C in 1 °C steps. Values are the thermoelectric voltage in mV with the reference junction at 0 °C.
Basis: NIST ITS 90 reference functions as adopted in IEC 60584 1. Type N is Nicrosil vs Nisil: a more stable high temperature alternative to type K.
How to use
- Find the row for the tens of degrees, then move across to the units column: row 120, column +4 is 124 °C.
- For negative rows the column is still added: row −20, column +4 is −16 °C.
- To read temperature from a measured mV, add the mV for the terminal temperature first (cold junction compensation), then find the total in the table.
Notes
- IEC colour code: pink positive wire with white negative. ANSI MC96.1: orange jacket.
- Values are reference values; real sensors have a tolerance class (see the thermocouple tolerance table).

Frequently Asked Questions
What is the mV of a type N thermocouple at 100 °C?
2.774 mV with the reference junction at 0 °C.
What is the range of a type N thermocouple?
The reference function covers −270 to 1300 °C. The practical service range is narrower and depends on wire size and sheath.
Why do I need cold junction compensation?
The table assumes the reference junction is at 0 °C. At the terminals it is warmer, so add the mV for the terminal temperature before reading the table.
