No way to change to metric or change any other perimeters. Cannot calculate decimal places. There are better apps that give more options that are free. Very disappointed for a paid app. ### 1/5 — Waste of a dollar. Should be free. *2014-10-15* Thought it was better detailed and does not allow you to use proper hose sizes. So pretty much useless. ### 3/5 — Good *2014-10-11* The only complaint I have is 1 3/4 hose doesn't seem to work right. I used 1 3/4 as well as 1.75 and neither worked correctly. Any suggestions? Other than that it works well. ### 4/5 — Mike *2012-04-12* Drop down screens with hose sizes and common lengths of hose lays would be great. ## Frequently asked questions about Friction Loss Calc ### What is Friction Loss Calc used for?
