I have setup Imperihome on my Android phone and would like to configure the units on my rain gauge to show in inches instead of mm. I can’t figure how to enter the formula to convert it. I have tried * 0.0.0393701 and it does nothing. It seams like the formula is missing a symbol that represents the rain in mm. Something like R * 0.0.0393701.
Thank you, Mark
Try
val*0.0394
Bad copy and paste: 0.0.0393701. 
I tried everything that I thought of with success. Your suggestion worked perfectly! Project complete.
Thank you very much!
