Firstly, we messed up and we apologise – we messed up the mass conversions with the last update and the silly monkey who did it has had his backside tanned.

***We are SO-SO-SO APPRECIATIVE of your reviews so please keep them coming and also let us know if there any other conversions you’re after. We promise to add them ALL! Big promise I know but you can take us to task if we don’t.

In this update we also added a whole load of new conversions that you asked for in the emails and reviews we received. Plus there are more to follow in the future releases.

You can contact us by email – just go to our website – we are here and we listening!

In my job, this is one of my most-used apps. It covers almost every calc that I need.

My suggestion would be an Electronics section: Ohm's Law, power (including 3-phase calcs). Resonance, capacitance/inductance/reactance calcs would be a plus.

For the RF Engineering/Amateur radio folks, wavelength, L/C circuits, etc would be great.

Finally, how about adding some reference look-ups, like ampacity & resistance of various gauge wires, or tap drill sizes for SAE/metric threaded fasteners. (This could be an almost endless list!)

A big THANK YOU for providing an excellent app at a more than fair price!


I love your converter in has come in handy over a thousand times in my line of field.. The one thing I have never found and I am asking you guys to try and do this somehow.. Bc I know it won't be easy.. But can you guys do a electrical converter? 240 volt to 480 volt.. And so on and so forth.. It's just a request.. If you guys can't figure it out look up ugly's electrical guide and there's a lot of conversions in there.. I would just like to be able to look up the # rather than finding it in a dictionary of electrical crap.. Just a suggestion.. Again love you guys keep up the good work..

This App Converts So Much That St. Paul Is Jealous

Being an arrogant ethnocentric citizen of the U.S.A. who has been enslaved into using the U.S. Customary Measurement Units I find this app bringing me closer to my arrogant ethnocentric citizens of France who have been enslaved into using the Napoleonic Revolutionary Metric System. The chocolate and peanut butter of imperialistic movements in one easy to use App-etizing conversive concilience of equality. I can hardly wait for the update that will convert the unit of an Iota to what my salary is!
