My Crown batteries have a temp compensation coefficient of 3mV/°C. My mppt ‘wants’ the value in °F.
What is the conversion if any? I found this example but the math is not logical to me.
For temperatures below 25°C, adjust +0.005VPC/°C (or 0.003VPC per ̊F). For temperatures above 25°C, adjust -0.005VPC/°C (or 0.003VPC per ̊F)
The celsius to Fahrenheit conversion factor is 1.8. so 3mV/C / 1.8 = ~1.667mV/F.

Perhaps the real issue is why the BMV software doesn't allow for either Celsius or Fahrenheit in a dropdown option?
Crown does not include temperature compensation in Fahrenheit for some of their batteries.
Thanks
Thank you, I am familiar with Celsius to Fahrenheit conversion factor for temperature. My question is specific to Temperature Compensation Coefficients. The above example from discoverbattery.com refers to the coefficient of .005/C converting to .003F, which would not result from a facot or 1.8.
.005 / 1.8 is .00277777777777(etc), which rounds up to .003 if you're only using 3 decimal places.
