Question 1

What temperatures are used in industry?

Accepted Answer

Furnaces: 1000-2000°C. Smelting: 1500-1800°C. Welding: 3000°C+. Thermocouples measure high temps.

Question 2

What thermocouple types for high temperature?

Accepted Answer

K-type: -200 to 1350°C. R/S-type: 0 to 1600°C. B-type: 0 to 1820°C. Varies by material.

Question 3

Why does -40 equal -40 in Fahrenheit and Celsius?

Accepted Answer

The two scales have different zero points and scale factors, but happen to intersect at -40. It's the only temperature where °F = °C.

Question 4

What's the coldest possible temperature?

Accepted Answer

Absolute zero (0 K = -273.15°C = -459.67°F) is the theoretical minimum. It's never been reached, though labs have gotten within billionths of a degree.
