Best unit convert app
I looked through a lot of unit convert apps. This is the best by far. I’ve been using this for about a decade. Nothing better out there.
UnitConverter Pro
Published by: Motohiro 大森
Description
"UnitConverter Pro" is the best and most sophisticated unit converter for iOS. It covers 649 units from 56 categories used by various users from students to engineers in their daily life or scientific/engineering calculation. Multiple units like feet + inch are also supported.
◆◆ Simple and Speedy User Interface ◆◆
Only two taps to get a required unit conversion table! (1) Tap desired unit category in category list and (2) tap value field of any unit you want to convert from. Immediately, converted values are displayed for all the other units based on "1.0" of the unit you tapped.
When you want to input arbitrary figure, tap the value field one more time to display a numerical keypad, which is specialized for input numbers including exponential expression.
◆◆ Functional digital display ◆◆
Converted values are rounded with user-specified decimal place and delimiting every three digits with comma. You can change decimal place from 1st to 9th any time.
◆◆ Search for a unit ◆◆
Copy & paste unknown units as well as numbers you find in internet or papers. UnitConverter Pro searches the unit from all the implemented units and show you a converted value immediately.

UnitConverter Pro Reviews
Perfect
Excellent app; thorough and very easy to use. Love the way clicking the value initially imputes a 1. More helpful than one would at first realize.
Excellent
The best conversion app by far.
Good
Good
excellent for serious engineering-science users
This app has a huge variety of dimensions of measurements, and within each a large variety of units of measurement. The user interface is the best I've seen amongst the unit conversion programs, being both eminently usable and very attractive. Many unit converters suffer from awkwardness in switching from selecting dimensions of measurement to units of measurement, but such is not the case here - very easy and intuitive, plus the number of places shown is easily user-selectable. I haven't come across any errors. Looking at the organization of the units of measurement, the author appears to think first in SI units, then in imperial (UK) units, and lastly in US units, but as a US user I don't find much lacking other than obsolete units of measure from agricultural commerce (and if you're buying peaches by the bushel, you already know how much a bushel is). This is definitely the class act among unit converters for serious users, and is well worth 99 cents - kudos to the author. For the everyday user not needing this app's variety of units, I think Measures Lite is the best amongst the free unit converters.
Upgrade turned great to crap
This ap was the greatest converter I ever used. The upgrade makes you're enter every unit in every category. The developer says, "sorry for the inconvenience." Do not buy until the downgrade is reversed.
True professional app
Took me a while to find this one. Clean, comprehensive & quick.
Must have app
Awesome app best converter by FAR A+++++
Wonderful!
As an engineer, this is a fabulous iPhone reference. Very cool.
Excellent app
This does it all. The pop up keypad is perfect and has a (-/+) key for neg temps. I downloaded this with no previous reviews. I tried it and will be showing all the ME in my office. Buy it!!!!
