# Divide all values in ASCII table (or raster file)

I have a pile of ASCII files representing 5min radar precipitation sums. The information is given in 1/10 mm which I need to convert into mm for further processing. Is there a way of doing this, preferably as batch processing since I have more than 100 files? I tried converting the files to raster and use a con statement in the raster calculator (ArcGIS 10.5.1) which would not succeed...

• Are you asking "How to divide a raster by 10?"? – Spacedman Jul 12 '18 at 14:24
• The answer to most "Is there any way to do this?" questions is "Yes." Please edit the question to specify what you have tried and the exact error you received. – Vince Jul 12 '18 at 14:43

Con("timestep.tif" > 0, ("timestep.tif" * 0.1), "timestep.tif")
