Handy App - 1 Suggestion
Nice app, easy to use and pretty comprehensive. One suggestion would be to allow the user to switch units on the fly. Essentially, either while inputting the value or reading the result the user could simply tap and change the units. For example tap the units for pressure and change from psi to bar. I regularly work with vendors overseas and customers in the US. Conference calls are fun when the vendor tells me the the displacement in ccm and the customer is telling me the pressure in PSI and everyone is asking about the motor’s torque output. Of course they want the answer in ft-lbs and Nm.
