## What is Best Ideal Gas Law Calculator?

This awesome calculator lets you compute and modify the ideal gas equation PV=nRT using any of the 4 parameters as the free parameter and with different units for P, V, and T.

The convenient sliders let you see the effect of changing one of the independent parameters on the dependent one giving you a very natural understanding of how the relationship works.

Students, educators, researchers, and those interested in computational chemistry will all appreciate the convenience of seeing the computation recomputed for different units with a simple touch of the selector bar.

## Key features

- Calculate PV=nRT
- Adjustable parameters
- Multiple unit support
- Interactive sliders
- Educational tool

### 1/5 — Worst than useless!

*2015-04-07, version 1,4*

I wish I could get my money back.  Can't use it to calculate Boyles law.  PSI only goes up to 100, why??

### 5/5 — Fix submitted

*2014-07-31, version 1,4*

@Penn hit the lock icon for the one you want to calculate (that is, "unlock" the one you want to solve for), then move the sliders of the other 3 values to calculate - it computes as you make the changes. See my support site for a video example!

### 1/5 — Can't seem to get it to work!

*2014-03-18, version 1,4*

Trying to experiment with changes in volume, temp and pressure and I don't seem to be having any luck. Better instructions may help!

### 1/5 — Good idea except

*2013-11-08, version 1.3*

At least in iOS 7, I'm unable to scroll back up to the top of the calculator, making it useless. :(

### 5/5 — Finally.

*2012-08-16, version 1.2*

Worked great for me.  Had no trouble with the app.  Not sure what "agrenergy" or "mommum" had a grief about.  The sliders make it better than the other ones I've tried.

Update has finally fixed the keyboard thing so I can enter values numerically.

### 1/5 — Nononono

*2012-05-02, version 1.1*

Doesn't work

### 1/5 — Worthless!

*2011-04-01, version 1.1*

Don't waste  your time!

### 2/5 — Sort of works

*2011-03-30, version 1.1*

Easy to get wrong results as values don't always update reliably. Wouldn't recommend.

### 2/5 — Doesn't deliver.

*2011-02-11*

I'm a first year gas student for commercial applications and I must say this calculator doesn't deliver clear results. For 99 cents I thought I was getting something that would be easy to work with and displayed the results. Instead I find myself trying to make sense of it all. This calculator needs instructions and a second window that displays the reasoning behind the answer. And display the formula.

### 5/5 — Great App!

*2010-08-06, version 0*

Really like this app.  Numerous input options for each entry.  I like the sliders for manipulating the calculations...allows for quick variances in results.  Good job!
