For scientists & engineers only.

While Units can do simple conversions like mm to inches, it can do much more. Units actually performs dimensional analysis, keeping track of what dimensions certain units are in. For instance, attempting to convert pounds (force) to kilograms (mass) will give you an answer in terms of acceleration, just as Sir Isaac Newton said it would. (Multiply kg by g to get a kilogram's force on Earth).

Unlike free online unit converters, Units lets you expand its default database of dimensions, physical constants and astronomical observations by adding the ones that are useful to you and modifying its existing units to meet your conventions. It's always available in your pocket, instead of pulling out your web-enabled mobile device to realize your lab walls blocks most wireless internet access.

Units also gives you symbolic keyboard support that the iPhone's built-in keyboard does not offer.


• Dimensional analysis

• Database of most popular units, physical constants, astronomical observations

4/5 stars

A few minor issues, but fantastic otherwise

The database is excellent... Nothing else gets close. It's very similar to the unix program by the same name. I have one complaint - the plural form of units aren't recognized. Thus, 2 meters^3 ---> gallons doesn't work, but 2 meter^3 --> gallon does work. Confusing at first (the unix program handles this form just fine). Adding numbers and symbols through the iphone system keyboard is kinda annoying, but that's not the fault of the app (though i think there's enough room at the bottom of the app screen for dedicated # and math symbol input, with text getting added through the system keyboard through a "go to keyboard" key).

Overall, a first rate app that's accurately described as ***For scientists and engineers only***!

0/5 stars

Not Ready for Primetime, Even for Engineers

If you need a simple converter for English to metric units, this is NOT it.
If you need an intuitive application that doesn't require you to move between screens and remember abbreviations, this is NOT it.
If you are an engineer, surveyor, or normal person who needs an application to convert area measurements (acres, sq.ft., sq. yds, hectares, sq. meters, etc.) , this is NOT it.

So who is this designed for? Damn if I know.
