OK. I'll give this a shot.

Create a log file that has Inlet Air Temperature in the log.

Next view the log file using Vishnu Analysis.

Then click the "View" menu item and then click "Math Channels". A dialog box will open.

Click the "Create" button and enter a name for the channel like "Inlet Air Temp F".

Toward the bottom of the screen you'll see a buttons labeled A to H. These are variables used to represent channels in your formula. Click on the button labeled A and select "Inlet Air Temp" from the list of avaialble channels.

Next type the formula to convert degrees C to degrees F in the Function text box... A*9/5+32.

Finally click the "Save Channel" button. This process updates a file named "math_channel.ini" that resides in the same folder as "Vishnu_Analysis.exe" file. You can now select this newly created math channel in your log analysis / graphs.

Let me know how it goes. I could create a few screen shots if needed.

wow learned something new... complicated, but works.

OP you can change the converted min / max in the data properties to the equivalent F values. this will log in Fahrenheit.
