David, we have a discrepancy of 73.8 deg C in test problem 6 (type 'R' thermocouple) for all the values of v between 11.438 mV and 19.306 mV (8 cases).

In very many cases my rounded results differ from the tests by up to 0.03. I have no idea why. Increasing the accuracy in my calculations does not help. Would it be an idea to reduce the number of decimals to 1?

I concur with William: You may have an error in the second coefficient table for type 'R'.

Test problem 6 fixed.
