Duct Calculator for Android
Gr8 apps. Unit conversion is main problem.
Like the general layout and feel of the interface. Lots of separate functionality that could be useful, such as conversion of imperial to metric units or conversion of circular duct to square duct. Severe limitations in the actual basic duct sizing functionality. Input units are limited. Only m3/s. Can't see all parameters on one screen e.g. duct dia, air speed, flow rate and pressure drop Needs ability to switch units on input screen.
Metric with no conversion.

This ductulator doesn't use the imperial measuring system, it uses metric. Useless to me.
