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.

Great App!

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!

Sort of works

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

Worthless!

Doesn't work

Finally.

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.

Good idea except

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

Can't seem to get it to work!

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

@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!
