Why not take the published distance constant and convert to mm?

Or, set up a little test and calculate the constant by yourself?

By the way.......don't PUSH and use the pencil icon to add a subject line!

You can read about how to do this with the Ping))) ultrasonic distance sensor in Chapter 2 of Smart Sensors and Applications. The book is a free download here:

It shows you how to take the raw sensor reading, and convert it into inches or centimeters. Converting from centimeters to millimeters should not be difficult.

I·hope this helps!

·· Here is a small change that I did a while back for a customer who wanted to get the same measurements. You can use the following example to get exactly the program you desire.

I hope this helps,
