Mobile App

(OP)
Is anyone familiar of a mobile app that can do operations with common engineering units?
For example doing something like this would be great:
(5kN + 3kip)/5ft^2 = 3.5kPa

RE: Mobile App

If you want it to do the math, not just convert, I can only think of Wolfram Alpha. I cannot confirm that that it can do that exactly but i know their website is powerful and it is made from Mathmatica and Stephen wolfram.

RE: Mobile App

For what it's worth, Wolfram Alpha is telling me the answer is 39.5 kPa *shrug*

RE: Mobile App

39.5 kPa is the right answer.

RE: Mobile App

What situation would require you to do that - other than a homework problem?
Seems like it would be better to do the conversion yourself just to make sure you get a feel for the magnitudes.

RE: Mobile App

You might want to look at Frink

You certainly get it for an Android system because I had it on my phone for a while.

RE: Mobile App

The HP-48 series calculators and their successors can work with dimensions just like you showed plus do a whole lot more.

I have i48, an HP-48GX emulator [https://itunes.apple.com/us/app/i48/id329454950?mt...), on my iPhone and it works great. In fact, I just used it to calculate a pressure of 39492.9_Pa from your data.

The m48 app, which I don't have, includes several other HP models (https://itunes.apple.com/us/app/m48+/id341541461?m...). I also found an HP-50G app (https://itunes.apple.com/us/app/hp50g/id553279622?...).

Similar apps appears to exist for the Android platform.

RE: Mobile App

You can also just type equations straight into google and it will do the math and unit conversion for you. If you're working in force, make sure you use lbf or it gets confused. If you want it to spit out a specific unit you can tell it that too.

For instance type in

pi * 5lbf / m^2 in kPa

and it will give me:

pi * 5 (lbf / (m^2)) = 0.0698725017 kilopascals

as the response before the first search result. If you've got a quick search bar you don't even have to hit enter. It just shows up as the suggested result in the drop down.

Works on the phone version as well.

RE: Mobile App

Doug,
I hope that is a typo. If not, your spreadsheet is wrong. 39.49 is correct.

Yes, typo. I agree with the consensus 39.5 :)

RE: Mobile App

Do you have to do this on a mobile device?
There is a free program much like MathCad called Smath Studio.
I used the desktop version before and it works pretty well.
http://www.smathstudio.com/. But I just looked at their website. It seems that they have mobile app too.Good luck!

RE: Mobile App

I can't help with mobile devices, I've been looking for the same thing without results.

If you are working on Windows I highly recommend Smath Studio. I use it frequently for cross-unit designs just like your example.
